Hey Oreias,
I have gone ahead and entered a request for the feature you are suggesting. I would like to add that we do have GitHub/Source available to our users which allows you to build released versions of the engine, including specific versions like 4.7.3 for example.
GitHub
Follow along with this documentation to get your account set up for source to be able to build different versions of the engine.
Thank you for taking the time to submit this feature request, and we ask that if you have further questions or need assistance please let us know!
Cheers,
