Stopping and restarting poudriere

Is it possible to  restart a poudriere build session so it picks up
where it left off?

I mistakenly hit a control-c in the controlling terminal of a long
build and would like to restart it with minimum lost work.

More generally, can a poudriere session be gracefully stopped,
say for maintenance work or to run a more urgent job, and then 
restarted without loss of intermediate work?

Thanks to Mark Millard's help it does appear that poudriere is
usable and helpful on an 8 GB pi4. The learning curve is steep!
