How to recreate the old fbx import behaviour?

How would I recreate the functionality of the old fbx importer -
Specifically

Hierarchy Type = Create one Blueprint Asset
Import as Dynamic = true

I know I can use the old import interface with the command
Interchange.FeatureFlags.Import.FBX False

But I am interested in how I would recreate these with the new interchange way to do things.
For the “Create one blueprint asset” part I tried to add a single blueprint actor, but I wanted to added 200 meshes to the blueprint and couldn’t figure out how to add multiple static meshes at once. How would you recreate these options now?

Thanks in advance!

OK just selecting all the meshes in the outliner then using “create blueprint from selection” and then using the “harvest components” seems to give me the same kind of setup.
Now I just need to recreate the “import as dynamic”.
