Configure Project for Editor Playmode

Hello,

in the current Project we develop agains Staging and Production Instances of Servers and i want to make sure, that when using the Editor Playmode, the Project uses the Staging versions.

- We have a native lib for staging and another one for production. They get switched using the ImportSetting flag for Android.
- We have AdobeTracking, which gets configured by having the right version of of the file ADBMobileConfig.json

When building the Player i use the BuildPipeline to alter the Import settings and swap the config files according to the desired flavor/configuration

What i´m trying to achieve doing the same, BEFORE Unity build the Editor-Version of the player when hitting the Play-Button in the Editor. Whatever i tried seems to be to late and AFTER the player has been build.

Is there a way to do this?
