no. it is not a file format issue, but an issue of the molfile reader
API and how bond information is stored in VMD.
the fundamental assumption is, that bonds don't change (because they
don't in regular classical MD).

however, you can define a procedure that calls mol bondsrecalc and
then mol reanalyze and hook it via a variable trace into the animation
