I have helped people set up "computational steering" for scientific
workloads on a batch systems in the past

It is possible to run batch jobs interactively if that makes sense -
the batch system just 'farms out' the executable to a free machine,
and you retain the input and output terminal.
Funnily enough, the Wikipedia article has the example of population
dynamics, and it was for something similar that I set up the
computational steering.

Batch / load levelling systems have this concept - 'job dependencies'.
You submit a series of jobs, usually a main long wallclock time
processing step, followed by post-processing jobs which are set to
depend on the main job finishing.
You could set the dependent jobs to be held in the queue till the
opeator provides this sort of manual input, would be quite easy to set
