Plugin Help PermissionsEX How to inherit someone to group with a command?

So basically I switched from GroupManager to Pex due to it's compatibility with buycraft. So basically I have a Prison server. But the owner want's to add someone to YouTube and basically I need a inheritance command to add someone to more that one group like grounmanager does. People really think Pex is easy will it's really not to be honest.

Also like SubGroups like groupmanager but like pex command Like Manuaddsub (Player) (Groupname) but Pex does not have a command like that so please anyone know a command to add someone to a subgroup or inherit someone to a group like Groupmanager does but with only with a commad

You can just do a quick Google search to find the PEX wiki:

The command to add someone to an additional group is /pex user <name> group add <groupname> . It doesn't exactly make the second group a subgroup of the first one (so sometimes it gets mixed up on which prefix a person gets), but it's more like it just lets the player have the permissions from multiple groups. Basically, that command will do what you want, but depending on how you do your prefixes, it might mix those up a little.
