[Question] Querying AGN catalogues

Hello,
I have a question: When using the API to query new transients, apart from the score of the light-curve classifiers, is there a way to crossmatch with AGN catalogues? . For example the MILLIQUAS catalogue (https://heasarc.gsfc.nasa.gov/w3browse/all/milliquas.html)? If one makes a watchlist, it takes forever to query because of the large number (~ a million; hence the name :) ) of galaxies.

If there is a way that I am missing, please let me know. Else you might want to consider adding a crossmatch option (i.e. catshtm_crossmatch) to the API ?

Many thanks in advance!
