How to launch standalone game, without rebuild whole engine code?

When i press Launch in editor, it starts rebuilding whole unreal engine code… i dont need that, i want it to use incremental build, and compile only myproject files, like visual studio does.

How to do that?

Perhaps it makes full rebuild only for new projects.

I think, full rebuild happens for every new project.

Thats also sad, because unreal engine code is still unchanged, i will stick with single project now, so this is not problem i guess.
