I haven't tried this specificly with David, but I think it should work with him. Load the character, export the head only as a obj file, use only "As Morph Target..." in the export options. Now export each eye seperatly as an obj. Import all three obj files with all the import options un-ticked. Parent the eyes to the head, then save to a props pallet, using "Select Subset" to include the head and both eyes in the pp2.
