[PyMOL] How to make the dashed line having more dots?

[JunJun L. <lj...@gm...>]

Hello everybody,

I want to make a picture on which two close atoms are connected by a  
dashed line. I use the "distance" command to make the dashed line.  
However, there's only one dot to compose the whole dashed line. Is there a  
way to make the dashed line having more dots?

======
What I want:
Atom_A ---- Atom_B

What PyMol gives:
Atom_A  -   Atom_B
=======

One more question on the dashed line. Can I modify the dashed line  
properties, like making it stronger or more compact?

Thanks!

Junjun
