shortcut for custom palettes?

Hi!

Does anyone know if there is a way to assign shortcuts to custom palettes in painter 2019?

The organizer I see is listed under 'Customize keys' and can get a shortcut, but what about added palettes? It would be really nice being able to just bring the custom palette with brushes out every now and then, not having to rely on tab which smacks on/off all open palettes/windows.
