Panel.cfg mod for homecockpit

I have a homecockpit based on Prepar3D v4 and PMDG B737NGX that are working very good.

But,there is one thing I haven't fully grasped.

I have 3 screens behing my hardware MIP that the PFDs,NDs and Upper EICAS are undocked.to.

I have saved a scenario file,  after undocking and adjusting all displays to fit nice on the monitors behind the MIP hardware panel, that I load when starting up the sim.

This make everything to be set up correctly every time.

This works just fine, but there is one disadvantage with this solution. If I want to start from another airport or want to change airplane I need to do that

via the standard P3V4 menu.

So I am looking for a way to do this in just one step.

Now my question:

Is it possible to reconfiure the panel.cfg so that whenever I start P3Dv4 and select a PMDG NGX it will start up with MIP screen correctly aligned  as when loading a sceranio file.

hope this was clear enough.
