File versioning in GroupShare

In keeping with Trados Cloud/Team, it would be useful and logical to have persistent file versions attached to each step in the translation process, so that these can be viewed and downloaded after the fact, as opposed to the current way things work, where changes are superseded and not recoverable after another change is made to the same text.

This is especially relevant to track changes during Review phase, which we are currently only able to preserve by downloading the source file at just the right time, before the file is finalized and all record of these edits is lost.
