Any way to stop the initial embedding and resume at a later time?

[AZMCode]

I have been trying to do an initial embedding of a large repository (using grepai watch), and have found myself needing to shut down the machine doing the embeddings then resuming again.
However, it appears every time I do this, the progress is completely reset to the start.
Any way to avoid this?
I have already tried with the gob and postgres backends to no avail.
