st: Repeated Measures ANOVA: contrasts

I have longitudinal data (7 time points) from 8 subjects belonging to the same group. I would like to compare time points 1 and 2 versus 3, 4, and 5.
I used:
anova FMT time ID, repeated(time) bse(ID)
contrast time, effect
to compare time points mutually. (ID is subject ID number, FMT is my outcome measure)
Is it possible to create a contrast (e.g. 1.5 1.5 -1 -1 -1 0 0) to compare time points 1 and 2 versus 3, 4, and 5?
Thanks,
- Vincent
