In reference to selection set. I am using on R12 the following LISp routine 
in the menu.
[SELECTION A]^p(if(/=sela nil)(setq sela sela)(setq sela(ssget)));
to clear this selection set,
[CLEAR SEl. A]^p(progn(setq sela nil)(prompt"Group A 
Cleared.")(terpri)(princ))
Have this way established 5 difference selection set. It works for me. Anyway 
let me know how it works out.
