Specify multiple folder starting similar

I would like to backup Thunderbird profiles of users who have a username starting with “p”. (e.g. of username: p99032)
In Files included I set C:\Users\:\AppData\Roaming\Thunderbird\Profiles\* but it backsup all users.
Is it possible to specify the server to save only Thunderbird profiles for users starting with “p” ?

Server UrBackup : 2.1.19 / Debian 8
Client UrBackup : 2.1.15 / Windows 7

what if you put C:\Users\p:\AppData\Roaming\Thunderbird\Profiles* ?

the doc says : is like * , but it stops at folder level, my understanding is that it should work

It works but when I look the backup there are the folder of users not starting with “p” however their Thunderbird profile is not backup but there are files in their folder (picture)
