byte_test only on reassembled stream?

I currently have a rule that looks for something like: flow:established,from_server; byte_test:1,&,0x82,2; I have a payload that is a UDP fragment that is tripping this up where the bytes in the inspected position are 0x87 but on the fully reassembled stream (and what Snort logs in the pseudopacket) is 0x84. I'm really only interested in the value from the reassembled part of this, and not the bits in the data section of the initial fragment, is this working as intended? Is there a way to accomplish what I want (only match on the pseudo packet/reassembled byte stream?). Thanks, Duane
