Are you saying that you are logging to the same log files for separate
If so, an emphatic "DONT DO THAT" is in order. You'd get burned
sooner or later.
One solution is to log binary on all of them to separate dirs, then
use something like tcpsplice to sort them all together.
Then run a postprocessing snort with the -r switch to regenerate
logfiles how ever you like.
Something like the portscan detection can only be done on the first
set of detection.
