Not like that,

The case :

I want to check traffic from specific AS to each specified network.

Filter 1 :
src as 1234 and dst net 1.2.3.4/24 or dst net 3.4.5.6/24 or dst net 
4.5.6.7/24 .

This will work but not as intended
Because the filter statement from :

or dst net 3.4.5.6/24 or dst net 4.5.6.7/24 will accept any src as 
beside as 1234

So I should write the filter like this :

Filter 2 :
src as 1234 and dst net 1.2.3.4/24 or src as 1234 and dst net 3.4.5.6/24 
or src as 1234 and dst net 4.5.6.7/24

It would be more simple if I can write the filter like :

Filter 3 :
src as 1234 and dst net in [ 1.2.3.4/24 3.4.5.6/24 4.5.6.7/24 ]

That sintaks only applied to ip addresses.

See that ?

So right now I'm using the filter like Filter 2. It works but very long 
sintaks if you have 10 network or more.
