Hey i want to promote a person to a specific group on a track but don't want to do /lpb user {user} promote staff over and over again until the rank comes, how do i do it? is there a command like /lpb user {user} promote staff owner?

Ahh thank you :D i will close this now!

You can just /lpb user {user} parent add {group} if you want to promote directly to a higher rank

but then the previous rank perms wont be added to the person would it?
Like i have example1.example set on helper and example2.example on moderator
if i promote to mod the person wouldn't get example1.example unless they are promoted from it through a rank

you should set group inheritance.

Just use /lp editor and add using the "+" button

Ill check it out

If i set "Default" as the parent of "Owner" owner rank will get perms from the default rank am i right?

Yes.
Making default the parent of Owner will give Owner all permissions of default (And if default has any parents themself, also the perms of those)
