Is there a way to make a Subscription Plan available (or not available) to a select set of Joomla Groups that are not children of each other?
For example, I see that under the "Access" tab of a Subscription Plan configuration there are the following two drop-down settings:
Visible for Access
Visible for Group
I would like to make my Plan visible to two custom Groups, which I've created (one is a child of Public, and the other is a child of Registered). The end goal is so that not all Registered users will have this plan available for upgrade--only those who are assigned proper access.
Seems to me that I would need these single-select drop downs to be multi-select options instead so that I can select/designate my two custom Groups.
Is there another way to achieve what I'm trying to do?
