Is it possible yet to have Custom Counters for items?

Like the title states. Someone has suggested to me that I make a script that adds onto a new counter when a Bait item is collected, so you can have more than one Bait item at a time. Problem is, I don't know if it's possible yet to make your own counters. So, I ask: IS it possible yet?

You know, I was playing the first quest once, and I SWORE you can carry more than one bait o.o;

I don't believe so, but my information is several betas old. In other words, I have no idea.
