Ability to Use Regex $ Notation (Captured Groups) in Replace Field

[D-Maxwell]

Feature description

I wish we were able to use regex as a means to replace, reformat and refactor text besides being able to search for specific character strings.

Feature motivation

Say there are bits of the shape n\d scattered all around within a text document (e.g. n1, n2, n17, ...). If I were to wish to format those as mermaid graph nodes, as in n1[`n~1~`] (which I've now come to realise Notable does not support, as it would seem markdown is not rendered within mermaid blocks ; perhaps because it is disabled inside of code blocks in general ? Unless I'm missing an update which hasn't been suggested to me for some reason), then the regex operation I would run would be similar to the following :
search : (n)(\d*)
replace : $1$2["`$1~$2~`"]

However it would seem referring to previously captured groups through $ notation is not supported. I wish it were.
