No the Init thing isnt something that MoreCore can do right now.
My suggestion for a simple solution is to setup multiple /myinit rolls on the actor
Something simple like:
Init First Action
/myinit (p1)
Init Second Action
/myinit (p1)
Init Third Action
/myinit (p1)
After they finish their First Action they click Init Second Action and they will be repositioned in the CT.
This will not work perfectly with the Next Actor button if they end up needing to act twice in a row so the player and GM will need to keep an eye on it.
Also to not show a SUM in a roll the specific command is:
rMessage.dicedisplay = 0;
Search on that is various Rolls.
