[Users] Q: Saving multiple outputs at the same time

Hi,

I am currently developing a couple of plugins that share some
peculiarities:

a) they are computationally intensive (comparable to steering+++, or
worse),
b) they compute multiple outputs,
c) such outputs are interdependent, but not in a trivial way (i.e. they
can not be derived from other outputs alone, maybe in a post-processing
stage),
d) all of the outputs need to be generated and saved.

A meaningful example would be P and S impedance inversion, volumes cross
equalization, and more.

Now, the only way to create a seismic volume for each output, is to
re-run the job with the same attribute definitions, apart from changing
the output index.
If I have N desired outputs, I need to launch N jobs whose cost is
pretty much the same: suppose each job takes one week, and then you
realize that it might be useful to generate multiple volumes at the same
time, if possible.

Of course expanding the cluster will help minimize the problem, but it
still would be preferable to avoid redundant computations.  

The steering cube computation solves the same problem by generating a
multi-dimensional output in one go: would it be sufficient to hack the
job *.par file to achieve a similar result even for non-steering
volumes?
I understand that without a GUI support such approach would be error
prone, but if it works then it's worth knowing.
[BTW, a multicomponent volume would then need some custom plugin do
extract each component, but that's a minor issue; also export to segy
might need a change to allow an additional 'component' selection].
