Protecting wikis (Wiki Pro) with Membership Pro 2

Hi, I want to use Membership Pro 2 for protecting wiki pages. Are they compatible at all?
The Membership Pro 2 protection rules only allow me to select standard wordpress categories. While Wiki Pro only allows me to create "wiki categories", which seem to be a different set.

Hence, I cannot see Wiki Categories from within Membership Pro 2, nor I can see standard categories from within Wiki Pro plugin.

Any suggestions?

Thanks
