Segments are merged and not added after modifying a 100% match. Is this customizable?

Hi everyone,

It looks like when I modify a 100% match segment and I confirm it, the modified segment is not added as a new TU in the TM but merged to the original segment (with custom fields being added).

I would like to keep both versions in my TM : the orginal TU that was found as being a 100% match and a new TU with my modifications (and new custom fields).

Is this possible? Can I customize this behaviour in the settings?

Thanks a lot for your help and have a good day.
