shift + f popover menu is hiding notes that have to be fingered

A minor inconveniance. I’m fingering piano music. Broken chords from left hand to right hand and back, starting on the lower staff, then with “n” to the upper staff and back.
My little problem is, that the popover fingering window hides the notes that have to be fingered most of the time. So now I have to close the popover menu every time. Well, there are worse things on the earth, I admit immediately.
But can I do something about this, that the popover menu pops up above the upper staff e.g. ?

No, there are no options for the placement of the popover, I’m afraid, and no current plans to add any (though we never say never).
