elite subset with extra wine and cheese benefit

I'm wondering if anyone's tried using Tessitura's premiums function to handle an activity as a benefit, and if not, why not?

We have tried various methods of handling an elite subset our our membership structure who get a couple of extra wine and cheese parties for being young and desirable.  There are excruciatingly  few young and desirables involved, so we can't justify giving them their own campaign to track their additional benefits (er, hmm, managing it if it were created).  This situation wreaks havoc with IRS receipts. 

Thanks!
