Plans to Include Source Build in Launcher

Are there any plans to be able to include source-built engines inside of the launcher so that it can have seamless integration with code plugins bought off of the marketplace? I would like to be able to just “Add to Engine” and select my source-built engine.

It is currently extremely inconvenient to download and install a launcher version 5.4 engine to get the files necessary for building the plugin for my source-built engine. Not to mention the headaches associated with building things manually via RunUAT. (I wasn’t able to get a plugin working after 2 days of finagling).
