Allow text replacement in parameters

[rbrian]

Is your feature request related to a problem? Please describe. One limitation of text in Fusion is that you can't have a user parameter that's an arbitrary text value. The best you can do if engraving text is to use a {_.configuration}. However, configuration names are very limited, in particular no special characters. This makes it hard to have a configuration-dependent engraving that is, for example, "1/4 tsp". The closest I can get is "1_4 tsp".

Describe the solution you'd like I don't know what the syntax limitations are... but what I'd like is to be able to have something like {.replace{.configuration},"_","/"}

Describe alternatives you've considered No alternatives seem to be available.
