Identify which Role user is assigned to

Hello All,

Is there any way to identify which Role a user is added to?
Because based on the user role, we need to make a measure which would display values if added in Role1 else woudl display it as blank.

The main thought behind this is we need to have a column level security wherein a column value needs to be displayed only for certain users and for all other resources it should be blank.

Note: I cannot create a user mapping table within the modle as the users list is controlled within a DL by the business
