This solution is excellent! I modified it a little to match for empty $step and then continue, just in case there is a leading, ending or doubled “/“ and same for CONFIGURATION which will be my indicator to find the values where we expect a value replacement.

       if ($step === '' || $step === 'CONFIGURATION’) {
           continue;
       }


Great thing!

Thanks a lot to all!

Cheers, Nils
