Lack of interest Manually Upgrade More Than One Member At A Time?

[DRE]

I created a premium usergroup and manually promoted members by selecting the premium usergroup in their profile as a secondary usergroup. A couple months later I decided to use User Upgrades so that they can upgrade their account themselves by buying a paid subscription. Can you add a feature that will allow us to manually upgrade more than one member at a time?

I used this feature (manual user upgrades) in vBulletin as a price in contests ("one year premium for free for the winner") and on the other side I get some subscription fees for user upgrades in cash or as an amazon coupon and so I have to add them manually
