Not sure about LC8, but up until now, I've used the cantSelect property to
create styled background regions on top of which foreground objects can be
selected.  One example is the checkerboard pattern that's often used in
graphics applications to indicate a transparent background.  By enabling a
control's cantSelect and disabled properties, you can drag-select other
objects on top of that control without interacting with it.
