XF 2.2 Manipulate user permissions? [Solved]

[Robert9]

Can I manipulate the user permissions for one class/page?
Can I do something like:

getSpecialPermissions in XF:User;

class showMeThePageWithTheFlowers {

$visitor->permissionsCombinationId = getSpecialPermissions()

Can I do that and where/when to manipulate the normal permission system?

My fault. There is no need to manipulate user permissions. I had to remove ->viewable() and have what I need.
