Hello JeffreyT,
maybe ask a moderator if he can move this topic to the
Scenario Design (+AI/RM/Mod) Forum.
An ES member already replied in a thread about it a bit, but I almost lose overview in General Forum due to the high amount of topics.
RMS grouping seems to be a subdirectory where you can insert commonly used parts of an RM script, so you can include this part to all new RM scripts, if needed.
Regards,
M0nTy.
