Field Mask for System Attribute

Content

Hello folks!

We are trying to use System Attributes instead of Custom Fields for it is more manageable and allows export and Import between Test / Production.

The only problem we are facing so far is that Mask is not available for Text Fields System Attributes. We tried the Pattern attribute, it validates the content but does not create a Mask on the workspace.

Is there a way to do this? Use Mask for Text Fields from System Attributes on Agent Workspaces.
