[Feature] Ability to replace files in built engine from source engine

[NathanaelA]

This feature is designed more for a company than a user idea basically eliminates each developer on a team from having to have a source build of the engine...

• Have a single source build that builds certain custom pieces that the team needs/wants all developers have.
• Each developer has an official Epic built version

AMS checks a shared location (probably a network share) for any components (do this during launch???? or manual trigger???)

• It copies over and replaces the pieces from the shared version to the local developers version and caches the hashes to eliminate future unneeded copying of the same resources.

Source Shared Directory structure probably needs to be /{version}/engine/... so that when it is triggered it can look at the version installed and find any components for that specific version...
