Hi,

I want to create a lot of distance objects (in the hundreds)

script like the following, inserting the exact atomic
selections that I want:
distance distobj12 = (atom1), (atom2)
distance distobj34 = (atom3), (atom4)
... etc.
However, I will end up with hundreds of distance object
controls on the right side of the pymol viewer. I want to
have just a SINGLE distance object that contains all of the
individual distance objects combined.
That way I could enable/disable the entire object with a
single click, or change the color, etc. Hundreds of
individual objects would be unmanageable.
Is there a way to do this? Thanks,

This is a reasonable request, but no, it isn't possible right now -- sorry.
If it isn't necessary to be able to turn the distances on and off, then you
can name them using a preceeding underscore "_" so that they are omitted
from the object list.
But in fact one *can* still turn them on and off, with the "enable" or
"disable" command on the command line:
enable _dist1
disable _dist1
And it would be straightforward to put those commands within a loop:
# turn them all off:
for i in range(100):
cmd.disable("_dist1%s" % i)
# turn them all on:
for i in range(100):
cmd.enable("_dist1%s" % i)
Change "100" to whatever is appropriate.

Even though the scripting of this sort is flexible and will get you what
you want, I'd still support Daniels's suggestion. Grouping multiple
objects (not just distances) would be extremely useful because one can
split the objects into functional or logical units and collectively
manipulate their properties (e.g. color, state, graphical
representation) and it would be more interactive than scripting the same
functionality. I can imagine however, that incorporating object
hierarchy/grouping into PyMol may not be a trivial task...
