Wouldn't it be great if that dialog box included a convenient check box titled "Use only expression dials" to save all that clicking of the same checkboxes every time you save an expression?

An alternative would be to group expressions and non-expressions into hierarchies within the Subset dialog, so one could easily check or uncheck all of each group with one click.

As I said, Poser does not segregate expressions and non-expressions. And it can take awhile to recognize which ones are not related to expressions. (Some are obvious from their names, but some are not.)

Unfortunately some people, even a few who sell their stuff, still create character faces by turning dials (including expression dials) and leaving it at that. If everyone would simply go the extra step and make a single morph out of those dials, it would greatly ease the problem.

But even that single morph would still be set to zero in a saved expression if you didn't know to go into the Subset dialog and uncheck it.
