Hi Frappier,

This is not possible at this moment. Even adding a hook could give issues, if there are a lots of posts needs to be updated because of timeout.

I’m in the process of re-writing extended permissions, so that all these advanced functionalities can be achieved.

Next version has a few functionalities added to the bulk edit screen, which will allow you to update individual roles. But this still needs to be done manually after adding a role.

Thanks

Syam
