I’ve used this layout before. The workspaces feature can achieve this, at least when opening a project or template with the workspace activated. What I’d usually do, when setting up the VST’s to do this especially, is to open the plugins and move them to the window I want, then close them. That way, when you open them again, they should be right where you left them the last time they were open. I’d set up the other windows like this as well, with the piano roll (key editor) set on the monitor I want it to open to, then close it. After doing that for all the windows I wanted to situate, I’d save the template like that. That pretty much worked for me.
