Feature Request: RegEx in struct_field

[LMS235]

It would be good if you could use RegEx in struct_field.

Unfortunately you can't catch this via Bureaucracy, because "struct_field" ignores the RegEx (see https://forum.dokuwiki.org/d/18526-struct-bureaucracy-regex).

I don't know where it is more or easier possible, here or in the struct plugin, so a request at both places.

It would be more correct in struct.
