Suggestion Box

Greetings SM!

Is it possible to have a writing ML to tag users within a group without doing the individual USER WML Tag?
For instance, if we wanted to call the group member's attention for a certain post we are making, instead of mailing the whole group we can directly tag them. Perhaps something like:

{user:######,#}

######: Group Id
#: Member Level

This code will tag all level 4 member of the group.

Thanks!
