Good Day Basile-
Although the wild card did not work for me, I was able to apply rules to groups with a dash - in the name by adding them to a list.
If you notice, I added the complete group name (e.g. int-2).
Having this at your disposal you can create lists of groups or rules that apply to such criteria.
Please see image attached.
Thank you for you help.
I will deel with lists.
