Overlay public scRNA-seq datasets onto your embedding

Firstly a huge thank you for making ArchR. It's been an enjoyable experience analysing my datasets, which I never thought I would say about single-cell data.

One thing I have been wondering is once you have your embeddings and clusters that you're happy with, is there a way to download some public scRNA-seq or scATAC-seq dataset and overlay where their cells cluster on your embedding? I can imagine this could be to validate your cell types with a public scRNA-seq dataset that did FACS sorting on known markers prior to single-cell for example.
