Ability to save default overlay style for all sims

The VR integration uses the Master Overlay style in the absence of layouts for VR. When changing sim, each sim starts off from your default Master Overlay styles. To save tons of time and hours of customisation, it would be good if users could edit one Master Overlay, e.g. For iRacing, and then be able to make that the default Master Overlay for all sims. So, if you edit the Master Overlay for Standings for iRacing and change the style, theme and info shown, you could then select an option to make that the default Master Standings Overlay for all sims, for example. Without this, for the load of us that play many sims, we have to go into every overlay in every sim in Racelab separately and re-edit them all so we have consistency across them all in how we want it to look. Being able to edit once and make the default for all sims would save so much time and mean only needing to edit each overlay once and apply that to all sims.
