Link to custom form on "Add/renew Subscription" page based on User Group

We have two sets of customers coming from two separate public websites to our Amember website. These are:

1. Spanish speakers
2. English speakers

These two user groups buy different versions of our products.

We can send these different user groups to the respective custom forms that we have set up in Amember, so that Spanish speakers see the "Spanish signup form" with the Spanish version products, and English speakers the "English signup form" containing the English version products, from where we add them to a Spanish or English User Group using the hidden form field in our custom forms.

This all works very well.

However, we run into a problem when a customer who has already purchased something goes to their "Add/renew Subscription" button in their members area, which shows them the default sign-up form.

At this point, the user has already been divided into "Spanish" or "English" User Groups, and the products are all divided into "Spanish" or "English" categories, but I cannot see any way to select a signup form on the "Add/renew Subscription" page (for logged in members) based on either their User Group, OR the category (Spanish/English) of a previously bought product.

Therefore both sets of users are shown ALL the products, which gets very confusing for them.

Is there a way to display a custom form on the "Add/renew Subscription" page for logged in members based on User Group?

Thanks for your help Caesar, that worked perfectly .
