Is your feature request related to a problem? Please describe.
I want to bulk override permissions for command category
Now i need to do this manually for every commands and it is hard.

Describe the solution you'd like
Add command ?perms buld_override (command category/all commands) (perms level)
It should override all commands in provided category

Possible solution: Support command groups in ?perms add/remove/override.

For now, here's an eval that can help you:

?eval group_name = 'put name within these quotes, e.g. perms'
level_name = 'put group name here'

group = bot.get_command(group_name.lower())
for i in set(group.walk_commands()):
    await ctx.invoke(bot.get_command('perms override'), command_name=i.qualified_name.lower(), level_name=level_name)
