Vault 2022
ISSUE: I selected 2 dozen files, I renamed 4 and validated the others. The restriction below forced me to go back to the previous wizard page and then manually remove all the filenames that did not change.
IDEA: If the filename does not change then skip it during processing and report that it did not change.
This Vault's [Enforce Unique Filenames] is unchecked so that is not the problem.

On the Inventor Wish List we call ideas like this "JDI" (Just Do It) because they are very low effort and low risk and they improve user experience.
