no, but each graphics command returns the id of its object(s).
and if you write scripts in the form of the ones shown e.g. at:
you can easily keep track of them.

not as such. you could try using a second molecule and draw to
that molecule without having any representations for that molecule.
if you show/hide the second (third etc) 'molecule' the objects
should be visible or disappear.
