Regex within attribution group will minimize the user overhead of adding manually attributions to the attribution group.

When 10's or 100's of attributions are created with a naming convention (Example: End Customer Name) and all are added to a single attribution group, having a regex in this case will simplify the process of adding those attributions. Instead of manual selection, a single line of Regex will auto select the attributions created but also will automatically add the newly created attributions without the need of user intervention
