I know for - the most part - the Alteryx core data bundle is the only one part of allocate. It would be great if you could open up allocate to the user so we can add our own third party data sources. Just tell us what the requirements are to make our datasets ready for allocate and then we can load it ourselves. Then we can use the allocate workspace to query data in a similar way.
for example:
Geography(DMA,*)
Variable(CYADULT18P,CYADULT18P,False)
