Adding UE 4.10 to launcher with installed source version

hi. is that possible to add ue 4.10 to launcher, without downloading , just from installed source version with visual studio? let me say it like this, i installed ue 4.10 from source version, now i want to add ue 4.10 to launcher, like others in picture. if there is a way please tell me.

and let me say that, you can add it to launcher with copying extracted data to a folder that named 4.10 in your epic game folder, then act like a regular download in launcher, it just download 3.4 gb instead of 5.4 gb,

Hi khokialism,

Unfortunately we do not officially support adding a source-code version of the Engine to the Launcher at this time. We are investigating ways to make this possible in the future, and some users have found workarounds to do this. However, these are not official workarounds that we support.
