Select Pencil Lines Only (Separately From Strokes)

Hi,

it would be cool to have a function giving the possibility to select Pencil Lines separately from Strokes and vice versa. The function could be called e.g. ‘Select Pencil Lines Only’.

I imagine that feature to work like the ‘Select Strokes With Current Colour’ feature (Ctrl +Shift +A).

And of course, it would be best if that function could be applied to several layers at once.
