You are essentially correct.

The priest sacrifices slaves at the temple, then goes to the lab to get more.

Without a lab, you have to supply him manually.

While this is a nice feature, it doesn't remove all the micromanagement. You can't pool blood slaves (from the hunters) without stripping them from the sacrificers as well. You also want to maintain enough slaves in the pool to supply next months sacrifices, or you'll have to manually supply them again.
