Renumber doors based on their "to room" parameter - List Logic

Thanks Jacob. the below from @Mostafa_El_Ayoubi seems to arrange the graph in a much better way than me & it seems to work

Renumbering the door as room number

Hi man , if i have 3 doors swing inside the same room (e.g room number is L1-015, so the doors will have the same room number “L-015”) but they should have L1-015-01, L1-015-02, L1-015-03 how i can do it
