I was only vaguely aware of Qubicle's new(ish) QBT export format, which includes support for pivots and model tree hierarchies.
I found a small amount of time to add support for importing QBT files to PicaVoxel. I don't have time right now to do a full update release for PicaVoxel, and recent Unity versions haven't broken anything as yet, so for now I'm releasing the QBT support as an assetpackage.

I've tested it with QBT exports of the Qubicle test models, but none of those test models seem to have either a) an indexed colour palette or b) the use of Compounds as a tree structure. The importer should support both of those scenarios, but if you come across problems, please send your QBT file to firstname.lastname@example.org and I'll take a look.
