At the moment, there is no support for plurals and capitalization. A long comment explains why. Support could be added for that without a format change.

InsetCommandParams::getCommand, which is what is used

in createInsetMath_fromDialogStr to interpret the data

Fixing it, I think, would mean sub-classing

InsetCommandParams to InsetRefParams, and the overriding
