Yes, AccessFilter plugin is your solution.

S1 - S5 subscribe to the same message say

 <key oid='AccountWithdrawMoney' contentMime='text/finance'/>

which happens very frequently so that you need a round robin for performance
reasons.

S1-S5 can send some filter rule in their subscribe QoS which your
plugin uses to decide who will get it.

Your plugin registers itself for mime='text/finance' to be
only consulted for messages of this type.
