Output control command for custom rendering of certain variable names in the output

[Bersobis]

Hello,
The output feature of this software is really useful, but it has certain limitations. For example, variable names can't be rendered with a custom string superscript like in the case of subscripts or be rendered with overlines.

I had in mind a command where, for a specified variable, it would replace the direct rendering of the variable name and instead replace it with a version written in HTML or LaTeX specified in the command.

Thanks
