New Post: Custom token

I think this is possible with v2, but I don't have any dev setup of this old store, so you'll need to look at the code to find our exactly how. But with this store I would look at reusing an existing field in the DB table.

This code base is no longer under development, I suggest you try using the NBSv3 https://nbrightbuy.codeplex.com/

One of the reasons for the rebuild was to help with this kind of thing.
