Sending additional parameters from HSphere

Is there a way I can send some additional parameters (of course which 2CO supports) via HSphere when someone signsup?
It is because when someone signsup and goes to 2CO shopping the item description there shows something like as “cart-283034323” which is not meaningful and I want to make it something like “linux package”. And for that I need to send an extra parameter.

Has any reseller done that?

I have always seen the random ID like you mentioned.
