Hi Eric,
Unfortunately I recently became very busy, so I will not be able to
address this any time soon. However, the indexing behavior is self
contained in the `org-babel-ref-index-list' function, so feel free to
take a crack at that function. If you are able to implement your syntax
as described below I would be happy to help fold in the change.
Cheers -- Eric
