Stacking Token Uses in Token Shop (For All Event Shops)

I play a lot of league and I happen to acquire a lot of tokens from events and the missions and I only use my tokens for random champion shards and I think it would be much more helpful and much more easier if you were allowed to increase the quantity of whatever item you are getting from the shop. For example: I have 1200 Mecha Tokens and I am going to use it all on champion shards since I need more blue essence and champs. I would have to click on the shop 24 times and wait for this animation 24 times.

It would be better for everyone and reduce the time it takes to do openings and such if you were to increase the quantity of what you bought from event shops.
