User Matching on rules for Policy Manager

Hi Everyone,

I'm currently using Policy Manager, and I would like to create rules to match username patterns are process traffic accordingly.
I've combed through the documentation and apparently the user filter on Policy Manager should allow globs - I can't seem to get it to work through.

My username patterns are as follows:
B-00000 ==> B*
L-00000 ==> L*
P-00000 ==> P*

Does anyone have any ideas onto how to make this work?

Thanks for the help.

Carlos
