No, this was not implemented.

I was unable to come up with a solution that I thought was tractable.

I became depressed when I learned that each 'run' of alternate
conformations was completely independent. Assume that there are two
independent runs of alternate conformations. The first has m alternate
conformations ... the second has n alternate conformations. Then there are
m*n possible 'models' that could be generated. In the general case there
can be 'r' independent runs. Therefore, we cannot statically generate all
of the models.

I think that we would need additions to the scripting language in order to
allow one to choose which alternate conformation was/is desired out of
each run. There needs to be a way to 'name' each of these different
models.

implemented.

Jan is very interested in this subject and has made some recommendations,
but I was unable to follow his descriptions/recommendations and visualize
how it could be implemented.
