Rename schematic cell in Allegro Design Entry HDL

Hello ,

I am trying to find a way to rename a cell in Allegro Design Entry HDL and updating all the references.
For example, I have a design root dsp which instantiates the cell rom and schematic.
I now want to rename the cell rom to rom_1 and update all the references.

I did'nt find any hint in the documentation ( besides cdscopyshell, which does not run on Windows), so I suppose that this can only be done using skill.
So I would loop through the hierarchies of the schematics and update/replace the cell rom with rom_1. That should work, hence it is some effort.
But what about e.g. the variant file or other files like the opf etc. this also needs to be updated manually, so this will become a pain :(

Does anybody know an already existing solution on how to do this ?

Thanks in Advance
