Dear Mauricio,
  The default lengths used in the distance-based bond
search in VMD aren't currently controllable by the user, however this
suggestion is a good one (and one made by others previously) that we
intend to improve when time allows. The immediate solution to your problem
would be to:
  1) use a structure file such as a PSF file, or use conect2psf to create one
     if you're working with a PDB that has conect records.
  2) use Tcl or Python scripts to allow you to interactively add or delete

We intend to improve these mechanisms substantially, but our development
time is already maxed out with other activities, so it may be a while still.
(I have a large backlog of good things VMD should be doing that we haven't
 had time to implement yet)

Thanks for using VMD!
  John Stone
