Hi,

Looking at the documentation, you should be able to do it with the "match" and "fill" rules:

The optional key match makes partial replacement of the original value possible: only the matched part would be replaced with the fill character. The match value must be a valid pcre2 regular expression.

The tricky part is probably getting the regular expression correct. I'd recommend playing around with something like regex101.com and see what each pattern matches.
