Multi-Buy Option In Shop!!

Hi. Am just trading in some stars at the shop and its a pain in the rear, tbh.

Ive got just over 4000 bronze stars which I am upgrading to silver, then to gold. Trouble is you can only trade in 100 stars at a time which means its a case of...

*Enter shop
*choose 100 bronze
*confirm redemption
*enter shop
*choose 100 bronze
*confirm redemption

And repeat another 38 times!!

Oh and then I need to upgrade all the silvers too, which I currently have 1001... so I may be here for some time. Yawn.

Can we have an option to do this a bit quicker pleeeeeeeease???? Ta, Lou
