st: Deleting entire panel id/group if condition is true for first year

Dear listers.
Is it possible to delete a entire panel id/group from the set if a certain condition is true for the first year?
I'm trying to keep certain spells in my dataset, and by using the -tsspell- (SSC) I have managed to keep panel variables with runs equal or above 7 years. But, I also wish to keep panel groups with 6 year runs IF the value in the variable "category" is nonmissing for the first year (or actually every year).
Any thoughts?
-Andreas
