How to create object from external file (i.e JSON) and do NOT save those object in the map?

Hello,

For my project, I want to use an external file (it will be used only for debug) containing locations.

My goal is to be able to load this file from the editor/game and spawn specific actors from these locations.

In editor, be able to move those actors and update the location in JSON file.

I want to be sure to keep in external file “Debug” stuff.

Is there a solution for this case?
(The demand is to have debug actors, but without changing the current map)

Thank you
