I don't know what a MICS is, or why it would need the limits turned on, but I wonder if it would not surfice for your purposes just to turn the limits on for the entire document, this is easy to do, and there are several ways of implimenting it. You can swich on limits for the entire document by using "Use Limits" from the Figure menu, by using a pose file;

{

version
        {
        number 
        }

doc
        {
        useLimits 1
        }
}

or by including the doc section from the above pz2 in a cr2 just before the closing brace. All these methods will affect every character in the document, but as they change the paramiters for the doc not the individual figures, this change will not affect any cr2 saved from the document.
