[PyMOL] Unbond two atoms

Dear PyMOL users

Sometimes PyMOL draws bonds between atoms which are not supposed to be 
connected. I know it is possible to unbond them using "unbond atom1, 
atom2", however this requires to always select the atoms and rename the 
selections to "atom1" and "atom2", respectively. It would be great if I 
could just click two atoms (using the "Atoms" selection quantifier) and 
then have them unbonded. How could I do that?

Thanks a lot for any hints.
