Thanks a lot. That was helpful.
To close this topic, I would add the following recommendations (enhancements):
1) On the "Attribute Rules" Tab, make the "Existing Attribute Name" column as a Combobox so that one can easily find an existing attribute. Currently, one need to type and search
2) In the documentation, provide additional examples to illustrate concrete use cases of Custom attributes (using RegEx as well as the other Condition/Matching Operator)
3) Share some videos (and/or Webinars) that illustrate concrete examples and real world use cases of Custom attributes.
Kind regards
Haithem
