Remote files opened in other editor de-linked upon reopening WinSCP or Hostname chnage

There are 2 issues i am facing:
Issue 1:
> Login into session > open remote file in another editor(Notepad++)
> close WinSCP > Login again > now i see file already open in N++ is de-linked as i am not able save file and i have confirmed it by re-opening same file again from WinSCP and it is opening at another location ...AppData/Local/Temp/scp27268/ instead of old ...AppData/Local/Temp/scp19478/
> Login Session's details Hostname etc same always.

Issue 2:
> Login into session
> open remote file in another editor(Notepad++)
> remote disconnected due to network issue
> Login again with all same details except Hostname(ip) changed
> now i see file already open in N++ is de-linked as i am not able save file and i confirmed it by re-opening same file from WinSCP and it is opening at another location ...AppData/Local/Temp/scp31268/ instead of old ...AppData/Local/Temp/scp21478/

Is there any setting/solution to force specific login session to keep same Temp's dir and avoid above de-linking of previously opened remote files ?

WinSCP v6.5.3
