Is it possible to group same check in report?

Hi!

I have a test where I generate a random email in a feeder (random characters). I update a customer email, and afterwards I do a check (substring.exist) that customer email is indeed updated. However when this check fails, the report will be flooded with different error messages.
The email above was just an example, as I do other updates with other random data.

So my question is, if it is possible to group those errors in the output? So if one specific check fails, it will group those to a single counter.
This is how a part of my output might look like.

I suppose a follow up question is if it is possible to add a custom error message to a check? If this is possible, the grouping of errors would work.
