I am finding OMC and Boss very tedious to work in. Very little information flows from one table to another. If it Auto Grouped you by Cell Name or Cell ID, that would be a great help. But just putting the currently connected Cell Name or Cell ID on the CPE > Register > Device CPE Table to help Assign to groups would be a major improvement.
Either Auto Grouping by Cell name or Cell ID Or show Cell Name or ID in CPE > Register > Device CPE Table
