Number of products can be submited in djc2 frontend according to user group and subscription

The actual configuration possible is to set a number of products that a user can add in front end. As a superuser, I can ad products in back-end but can't edit or add others in front-end.
In other hand, If you want to sale subscriptions and by subscription type, user can add the allowed number of products according to his assigned group.
for example I want to sell a :
Gold subscription. users of Gold group can add X products
Silver subscription : users of Silver group can add only Y products.
and so on.
