Schedule trigger on previous build chain

Here is our current scenario, we have four build configurations - promote, provision, deploy and finalize which all have a dependency on each other as such: promote -> provision -> deploy -> finalize. The promote step has to be pushed manually for it to promote from one environment to another.

We are trying to setup a weekly schedule on provision but do not want promote to promote the latest changes but since there is a snapshot dependency on promote it always re-runs the build. Is there any way for me to setup a schedule on a previous build chain that ran?

Thanks,
Adrian
