Is there any way to return the coarse-grained beads to atomsin the martini3 force field?

GROMACS version:2022.3
MARTINI version:3.0.0

I would like to reconvert the coarse-grained to the underlying and recalculate.
I checked the tutorial and the situation is that only a charm36 backmap is only provided for martini3.

4: Backward.

I want to convert from martini to gromos because I want to recalculate in gromacs.

I would appreciate it if you could tell me if you know how to do this.

Thank you.
