When validating I want make use of Regular expressions. However they are not available (like enum/constant) in the microflows. So I have to put the Regex as a string in the valdiation which is something I rather avoid if I want to use that expression again.
I need this :-)
Upvoted all open ideas, concerning this matter. For sure, with reusability in mind, you want to manage your regular expressions in just one place and have the ability to use them anywhere. But being unable to use them in the IsMatch function really seems a bit odd.
