Post-delivery fails with newer snapshot

The RTC Post-delivery is working as expected, but I am hoping to get a work around to the problem below:

We currently have an environment where we run an integration level build on each of the components in the integration stream. If the build is successful we post deliver to the release stream.

In some instances we get the following message from the post delivery step:

2012-04-26 23:45:38 [Jazz build engine] Invoking post-build participant "com.ibm.team.build.autoDeliver"

2012-04-26 23:45:42 [Jazz build engine] Aborting post-build deliver. It was determined that build "8000-Integration ComponentB 20120426-2307" has already updated the deliver target with a more recent snapshot than this build's.

The failure is caused by the build sequence:
- Build Component A start, Snapshot is produced
- Build Component B start, Snapshot is produced
- Build Component B - finished successfully, Snapshot delivered to the release stream
- Build Component A - finished successfully, The post delivery function determines that a new snapshot exists in the release stream.


The behavior in general is what would be expected. However, in my case since the snapshots contain only the component which was being built, I would like the post delivery function to deliver based on baseline contained in the snapshot compared against the content of the stream's baselines.

Or, is there some other way, which the snapshot/baselines can be delivered to the release stream on a successful build?

Thanks
