How does everyone handle adding pre-order titles to their database before the physical release arrives?

Hello! How does everyone handle adding pre-order titles to their database before the physical release arrives? I like entering them early so I can track what I’ve ordered—some take months to ship—and so I can fill in personal fields like date purchased and cost while the info is fresh.

For example, I’d like to add TerrorVision’s upcoming Best Worst Movie 2-disc Blu-ray (link below), but it isn’t in the Core database yet.

Has anyone found a good workflow or workaround for this? Thanks!
