Applying a TPS proc to a subset of routes

I have a situation where I have an IN ADT thread with quite a few routes going out. However only a subset of those routes I have to apply a couple of TPS tcl procs. These proc are actually opening a tcl socket with an SQL server and sending a query and getting reults and including those as DG1 segments in those ADTs. I do not want to do this for all ADTs, only certain ADTs and only for certain routes. Is these a way I can apply TPS tcl procs to a subset of routes ? One way of course is to take all these routes to a common OUT and have that OUT go to a another IN and apply the procs these as pre-TPS but I was looking for another way without creating an additional two threads.
