Best way to do a review between in-house translators


I'll be doing some reviews for other Trados users in my company and though I've played around with checking xliff files, they've usually been after the translation had been produced and was just to update the TM data. So, could someone point me in the right direction for simple, step-by-step directions for how to send (share?) a file for review, then how to open it, then how to send it back, have the original translator reflect the changes, then generate the target.

We use Studio 2017 and we have shared folders we can access. We don't use Groupshare and all TMs+TBs are locally stored. I'd prefer not to use the "export to review document" because we wouldn't have the valuable TM/TB and verification functions available in the Editor view. 

Should projects packages and return packages be made? (Prefer not as the translators are relatively inexperienced with trados)
Should we just share the contents of the project folder? I'd open the project then inevitably get a bunch of errors saying it can't find the locally stored TM. Then I'd review it, save, then return the.... entire project folder back? Or just the xliff? Then they'd get a bunch of errors too when opening their project saying they can't find the locally stored resources I had on my computer. See what I'm saying? I'd love for it to be as simple as "send me the xliff file then I'll send it back to you. Then double-click the xliff file..." but I fear it may be more complicated.

Ideas welcome.
