One easy way to accomplish what I think you are after above, esp since 
you are obviously alraedy familiar with DAGs, is to use "nested" dags. 
Note that a dagman workflow includes "nodes" that are Condor jobs, and 
one of those jobs could be a dagman job.  So you could take your 
existing DAG "foo", and make a new DAG that does notify_start -> submit 
DAG foo -> notify_end.

Take a peek in the DAGMan part of the manual, specifically
