[Membership] custom post types protection

I gave access to users via Membership plugin to create posts and custom posts on my site.
They have access to dashboard to do this. But they do not have access to membership tab, which is obvious.

I have two types of memberships set up on my site.
In my custom post types I have two categories, for each membership.
After someone add custom post type to first category, the members from second category have access there (in default categories/post they can protect this via "Individual Posts" which gave box on right site).

The "Individual Custom Posts" does not offer this box.

Walkaround for this is to use "URL Protection"add on which can protect category URL for those custom post types.

Is the any way to include this protection box in next version in custom post types?

Thank you
