Fast change Permissions

What I mean by Fast change Permissions is that in bedrock, you have to manually change someone from visitor --> Member ect. What Fast change permissions could do is this: (example)

/Perm (m, member, operator, o, v, visitor, c, custom) (@p, @a, @s, @e, @r, ect) | canFly | | canTp | |breakBuild | | can chat | | canOpen | | canKill | ect...

the options in | example | are there if you do /perm c(custom) (@s, ect), then you can pick custom options. The reason this would be helpful is because if you are doing a PVP map, but in the lobby don't want people to attack each other, you could use this command. It would mostly be useful for mapmakers and servers. ^-^
