@dabail10 and I were talking, and we probably want a CICE modifier as well (e.g. CICE%REGIONAL). Now that open boundary conditions are available in CICE, he's going to test that code out but eventually CICE will want to be able to configure regional domains.

Two notes:

  1. I assume changing CICE to CICE%<something_else> will not change answers if CICE's config_component.xml doesn't know what to do with the new modifier, but it's worth testing that hypothesis
  2. CICE%REGIONAL is my first thought, but @dabail10 may propose a better modifier

Maybe this should be another PR? Or can CICE use the MOM6 regional? Because you can't have one without the other?
