I've noticed that sometimes when I'm inserting multiple entities of the same type with hasdata they will each get their own insertdata command. Other times I've seen it use one insertdata command and list multiple items in the objects parameter. I haven't been able to track down the pattern for what results in one or the other.

Here is a screenshot of a migration wher eyou can see that brewertypes are combined into one insertdata command but down below there are two separate commands for inserting 2 Units (the 2nd one is chopped off in the screenshot).

One difference between BrewerType and Unit is that BrewerType owns an another type via OwnsOne --which is supplying some of the values for each of those rows. Is that enough to make the difference?

Figured I would ask rather than continue to try and try.

Thanks!
