[Request] Permission Sets

I would like to be able to create a permission set by choosing what the roles then permissions by role then selecting which channels to apply the set to. I'm currently splitting out my server into PS4 and PC channels with every channel locked down so members have to select one of those roles before accessing any server channels, and seperated activity recruitment channels by platform. This means each channel I have to create the PC and PS4 roles, then go to each channel/ category and add the PC role permissions, then add the PS4 permissions, then remove the @everyone permissions for each channel. If I could create a permission set with those three roles then be able to select the channels it applies for it would be much more user friendly.
