SQL connections sometimes seem to time out while building TVPs for our bulk actions. We can pre-build them, so we should.

This is a bit of an exploratory fix since it has to do with connection timings. I wasn't able to reproduce locally, but hopefully we can test it out prior to merging

Going to hold on merge until @kendratodd can test on her setup that's complaining about this.
