RTC/Jazz Source Control fetch Changes

I have a requirement where my build system (RTC/Jenkins integrated) should conditionally accept the changes. Say We have component/folder structure below. Here, component A is RTC component

Component A :
   Folder A
      Folder A1
      Folder A2
   Folder B
      Folder B1
      Folder B2

Internally, we have a process which ensures we do not have deliver change set which has changes to both the folders (A&B). My integration build A should  trigger only when there is changes to folder A and integration build B should trigger only when there is changes to folder B. Is there a way we can achieve this using RTC extension points ? Please advise.
