My apologies for just now responding. After conferring with the committee, you might want to investigate Viewplus’ Tiger Software Suite (TSS), which uses liblouis and Visual Basic add-ins for Word and Excel. Later this month, on March 31st, the CAT Committee is presenting a webinar on TSS, but with an emphasis on math transcriptions. This webinar will at least give you some perspective on the program and, if attending live, then you can ask specifically about these features. I hope this helps.
