OBJ Import - Split AND keep vertex order

Hey guys,

Is there a way to have the importer set to “split” but still keep the vertex order if only one mesh is imported?
I often import and export stuff between different programs and Blender.
If I import something from ZBrush I want it to keep the vertex order.
If I import multiple objects I want Blender to split it into several objects.
Why is there a difference in importing? I never saw this in any other program.
They just keep the vertex order and split it up into several objects if there are some.

Is there a setting to have the same behavior in Blender?

Cheers Chris
