Configurable Generic Error Message

It would be fantastic to have a configurable action in runtime or somewhere in settings to call a microflow instead of showing the "An error occurred, please contact your system administrator." generic message. It would help handle unexpected and unhandled errors much more gracefully.

I understand that we can edit the text in the popup but wouldn't it be great to have the action configurable instead of just the text inside popup?

We cannot error handle everything so handling them gracefully via a custom action would be really really helpful.
