Integration of separate single nuclei RNASeq and snATACSeq datasets

[GDS97NYC]

Hello! I was wondering whether it is possible to integrate separate single nuclei RNASeq and snATACSeq datasets.
I have generated a snCUT&TAGSeq datasets and would like to use the data provided by the Brain Allen Atlas to preliminary annotate my clusters. Similar question is.. when I will run a single nuclei RNASeq from the same cohort, the cells are gonna be named differently anyways. How do I address this?

Thank you so much!
