Use full regex in Redirect Domain module

Problem/Motivation

We're just moving 4 domains into 1 new and the Redirect Domain module solves many cases. It would be even better if we could use the full scope of regular expressions instead of just * (which is actually replaced in code into .* and used as regex too).

Steps to reproduce

Would be nice to do something like this and use named capturing groups.
Sub path:
\/(?P<lang>[^\/]+\/)?foobar(?P<version>[0-9]{4})\/[a-zA-Z]{2}\/(?P<id>.*)
and destination:
/<lang>doc/foobar/<version>/<id>

Proposed resolution

Instead of using cores https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Path%21Pa... replace it with custom functionality or at least allow switching to advanced more.

Maybe also checkbox after "Sub path" input enabling regex for that particular field could be an option?
Something like this This would allow adding new feature with backwards compatibility. Maybe most people don't want such a feature either so it would be best for all.
