[Question]Building project and rolling out updates

Hello there! I’ve currently stuck in this situation: I made a project with some levels and blueprints. Then I went to build project and built it for Win64. (Side note: I unchecked box that forced build module to build a game in a single file).

I did some changes to my game but I want it to build it now as an update. If I deselect “Full build” check box, build module still builds an entire game. Any suggestions?
And I want engine to build updated files only. If possible…
Thanks in advance. Denuro.

There is some documentation that covers that: http://docs.unrealengine.com/latest/INT/Engine/Deployment/Patching/

Thank you very much!
