Play Sequence on random Fixture

[pgmstt]

Hey,

i got a Question, so is it possible to create a Sequence, wich is applied to a random fixture.. I'll give you an example:

I got 20 LED PAR-Cans and i want them all to be red. Then i want that only one of those PAR-Cans strobes blue one time, after that another (randomly selected) should strobe blue, again. So they should strobe randomly in another color but never together. Is there a possiblity?

Thanks

erm.
Create a sequence with one step for each fixture and set one different fixture to strobe per step, give it really long step time. in the cue window set the sequence to random.
?
