How to make a group of databases

I am experiencing a problem with grouping databases !

Databases- 1. lbsinsti_lbs 2. lbsinsti_mera, 3. lbsinsti_merabachpan, 4. lbsinti_school, 5. lbsinsti_vijayvergiya, 6. lbsinsti_vvbv

I want these databases to be grouped in a single directory or folder

But now It's showing the all 5 databases in the main directory. Please Help! Thanks in advance !
