BPM Correlation Condition

Hello,

I have created a NW BPM pattern to collect multiple messages (2 messages of different type using correlation condition) and it's working fine.

But now i want to formulate my correlation in such a manner that any of the two intermediate messages used in BPM pattern can initiate the flow and eventually correlation for the second intermediate message.

So wanted to ask that can we use OR operation under correlation conditions?

Something like this:

Intermediate Message 1 -> correlation condition -> Count2 = 0 OR MT_Message1/Record/Id = ID_2

Intermediate Message 2 -> correlation condition -> Count1 = 0 OR MT_Message2/Record/Id = ID_1

Thanks
