Combining annotations from multiple references

[stanleyjs]

Hi,

Is there support for aggregating annotations from multiple references?

For instance, we have some brain data that is not exactly the same region as the Allen human cortex you have provided. We also suspect the presence of endothelial cells and t cells. We would like to run the same query through multiple references (for instance multiple custom Allen references and a PBMC reference), collate the results, and then choose the "best match" from the multiple alignments. Is there a recommendation for how to achieve this or similar results?
