I need to attach variables to my virtual goods but I can't find anything related to that on the forums.

I know there are properties, but afaik they are constants to attach to your virtual goods, what I want is to attach a variable, i.e. expand the virtual good description, especifically, add a locked status (boolean), and how it was won (integer (enum basically)).

Is there anyway this can be accomplished on the platform, and how?

I personally dit it in a meta collection.

As a trick, you can put some json in the tag, or use unused virtual currencies to add numbers (but not very clean).
