Would it be possible to have the exporter work with multiple instances of bookstack?

Currently I'm just running 2 instances of the exporter, one for each of my bookstack instances, but it would be nice to be able to just have 1 instance of the exporter. Is there possibly a way to add second instance to the config.yml and just have it read sequentially.

This may be one of those "more trouble than it's worth" things.
