Is there any chance of getting the Time Away settings to function in the same way as the old Holiday Settings?

I'm trying to have a couple of days off during the postal strikes, but when I try to set this us so eBay don't promise my customers next-day delivery for second class post, this is what I get at the top of the page:

Delivery dates may not update for select items on Time Away

Whether you choose to allow sales or pause them, you may want to change the postage format or the dispatch times on the following items while on time away: Second Chance Offers, Auto-accepted offers, Pending counter-offers, Seller initiated offers, items with collection in person, Click & Collect or Global Shipping Programme, and digital items.

Seriously?

Before I can take time off work, I am expected to go through all my listings and remove click and collect, GSP, collection in person, and switch off auto-accept on Best Offers?  

Who at eBay thinks that this is reasonable?  Or that it makes more sense to expect sellers to know about this, and to change ALL their postage policies or the postage on ALL their individual items, because the eBay Programme Streamlining Team can't manage to find a way to make holiday settings apply to all a seller's items?

This is taking one burden off the incompetent programming system, and shoving it on to individual sellers.  With the penalty that if anyone is reckless enough to take a whole week's holiday, and forget to alter the postage for ALL their 7000 listings, they may come back to find that eBay has allowed buyers to claim Item Not Received for stuff that sold while the holiday settings were switched on - because the buyers chose the Collection In Person or GSP or Click and Collect options.

This didn't use to happen under the antiquated system.  It applied the holiday dates to ALL items, except ones which already had bids or live offers at the time the holiday settings were switched on.  And it didn't crucify sellers by allowing cases to be opened and automatically closed against them for items which sold while the seller's holiday settings were on.

Surely it makes sense to apply the holiday settings to ALL the seller's items.  Not make it dependent on the delivery/collection option that the buyer chooses!

It's like telling your staff that they can have a fortnight's annual leave, but they'll be punished if they fail to:

- answer any letters that arrive at their office and have first class stamps on.

- answer any phone calls made to their landline by customers whose Christian names begin with a vowel.

- scoot into the office and stand to attention at their desks if there is an unannounced visit from a senior manager.

Seriously, is there any chance of sorting this out?  It can't be impossible, because it's been done in the past.
