Accessing a separate DataModel from a plugin?

Hello,

Is there a way to access a separate DataModel from a plugin script?

To be more precise, I need to have one script run in Edit Mode’s DataModel, detect a new Playtest DataModel and access that same DataModel.

Basically, I need to access and change some stuff in the Playtest DataModel as soon as the user start playtesting (even before the loading screen appears), I can’t rely on the Plugin that runs only in the Playtest DataModel since it loads at the time the Player connects and I also can’t rely on the Plugin that runs in the Server DataModel (since I need to make changes only locally in the Playtest DataModel)
