In our organisation we use the Copy User Attributes feature when creating new starters to get the group memberships for a number of different template accounts based on where the user will be working. 

We now have the need for provisioning a group membership depending on what device they will using. I can add a custom attribute and creation rule that sets this group and works but only when not using the Copy User Attributes feature. 

It appears as though the group memberships can only be changed by one of these features and they do not work in unison. Has anyone come across this and/or worked a way around this. I do not want to have to create multiple templates for all our sites.
