Can we get Royal Mail 'Saturday Delivery' integrated so we can offer it as an upgrade option?

Quite often have buyers expect saturday delivery when they order 'next day' services like Tracked24 or SpecialDeliveryGuaranteed1pm on a Friday, and having it a separate option/upgrade with an additional fee would help with clarity, and also be nice to offer to other buyers who might need it.

Even if instead of integration it was just an option within postage policies listed as "Saturday Delivery"

I hate Saturday SD.  It's not available online so I have to create a label and pay instead of just chucking the parcels through the hatch and waiting for the PoP. 

My eBay buyers never take the Mon-Fri SD upgrade, so I doubt that they'd pay the huge extra charge for Saturday delivery.

It is worth noting that if you are on a RM business account then Guaranteed Next Day Delivery includes Saturday delivery at no extra cost.

It is only if you buy it at the post office or online that you have to pay extra for Saturday Delivery.
