Events inventory of add ons

PLEASE bring back the inventory abilities in the new Events. You have the options to have multiple versions of an add on, but no longer can I put in the inventory per item, instead it is a total inventory of all (ie: I give away 800 tshirts to 800 volunteers every year. I can no longer put in how many S, M, L etc. I have so that once they are gone folks have to choose another size, etc. PLEASE!
