Run from command line under one process server + game

How to run from command line using one process ?

 UE4Editor.exe My.uproject -server && UE4Editor.exe My.uproject -game 

works fine, but it runs two separate processes, meaning it can’t be just Alt-F4, edit, re-run :frowning:
(Instead it is, Alt-F4-F4 oh quacks I closed VisualStudio)

Editor has this nifty option

How to get that from command line?


Ps. Not sure if this is the appropriate sub forum, apologies if it ain’t.
