Ue4editor : launch server on a different directory

Hello it seems that launching ue4editor, it will search in “Epic Home”, the project (exeample : c:\Epic Games\4.9\MyProject\MyProject.uproject).

For different purpose, my project is elsewhere on my drive, in another directory.

Can I use command line to indicate on which directory is my project? (ue4editor c;\dev\udk\myproject mymap, for example?)

Not possible it seems
