Are the Published Segments being used in Experience Cloud?

Like maybe a few of you; we have exceeded the 75 published Segments due to a previous user clicking the "Publish this segment to the Experience Cloud" on over 300 custom segments in a single report suite. I can't wait to audit and turn this off on all but about 7; I'm sure I'll find a way to do it in batches to make it easier.

The question though: Is there a way to know whether the Segment is actually being used within the Experience Cloud? Even though our adoption of EC is low, there may be a few of these segments that are being used in Target for promoted test winners and maybe experience targeting.

The segments have all been built using Analytics, we do not use Audience Manager (yet); if that helps. Thanks in advance for the help!
