Allow importing many assets from a single blend file.

It'd be very convenient from a workflow point of view to be able to store all my assets as separate objects in one (or a few) asset blend files (think of them as packages of assets) and import objects individually from those, using the object name instead of filename.

You could also show the thumbnail from the data preview instead of having to generate it.

+1 for adding many assets from the same file. Imagine having to import ex. this set, one model at a time: https://sketchfab.com/models/9ec7a14729aa490fa712e51c217db0f5

An option to render the thumbnails textured(in color) would also be a nice feature. Ex using this set: https://sketchfab.com/models/4cf6f452719c4363bab5faddbc221391
