Duplicate test case handling and overwriting ability

[MurphyRA]

If I import a test case file a second time, I get the same test cases uploaded again as new test cases.

Is it possible to activate a unique key on the "Name" field so that I can then have the choice between (a) not uploading and (b) over-writing the TCs which are already there?

Or is there another way to handle this?

I have asked this question too, but not had an answer from support. someone suggested that the process is not parsing special characters correctly and therefore does not recognise the test case as already existing. I would like more information in this

I did read something about there being a problem importing test results when there is an underscore being used in the name, but the examples I have tried do not use special characters.

Oddly enough, I am convinced that I previously saw an error message when validating a file which had already been used, but I cannot recreate it.

Has anyone else found a way to handle this issue, please?
