The answer, unfortunately, is no, not easily/directly.

Such things - allow for multiple actions, popup menu, etc. per
button or tool-bar icon (e.g. via modifier keys) - was requested
long ago, but never got anywhere.

What you can perhaps do as a workaround is to bind a single
command to a button click, and have that command test the event
that lead to the command invocation and then dispatch different
behaviors depending on the event characteristics.
