John,

While the structure of the DAG must be defined in advance (e.g., A runs 
before B), the details of the individual jobs do not have to be settled 
until the moment they're submitted by DAGMan [*].  So yes, you can 
submit a DAG where the submit file for job B is almost empty, and job A 
(or its POST script) can in fact define job B's details.

[*] the one exception is each job's "log" file specification -- that is 
the one submit file line that must be exist for each job at the time 
the DAG is started.
