Rename (Renumber) First Cohorts

Dear Forum

Is it possible to renumber or rename newly recruited Marian First Cohorts? The newly established unit has roughly a name like “First Cohort Legion_” and I wish to rename the unit in “First Cohort Legion I” etc.
Is there any possibility to accomplish this?

Best regards
Marcel

I just read in some other posts, that the „First Cohorts“ are numbered automatically when the „Legions come along“. What does this mean? My first “First Cohort” is already in a stack with 8 Marian cohorts and still does not have a “legion number” (i.e. I)

Regards
Marcel

Only cohorts trained in Rome get the numbers, as far as I know.
