How to always "play this level" in the "viewport 2" window?

Dear Community,

I want to know how do I make the unreal engine always “play this level” in a particular viewport. I have checked all of the modes provided. The closest options I got are…, but…

  • Selected Viewport: sometimes I have my mouse in the wrong viewport and “alt+p”. Then the “view angle” I want to preserve before I “hit play” gets lost
  • New Editor Window (PIE): I want to dock this window, but I can’t. Sometimes I also want to be able to edit while playing (I know there is simulation mode, but the same problem I encounter in “selected viewport” still occurs)

Thank you all in advance~
