GCO HA DR Question

Can GCO support following:

Multiple cluster at primary site with only one one node cluster at secondary site.

normally we setup GCO with one cluster at primary site (cluster A) and one cluster at secondary site(cluster B), and culster A and Cluster B configure to be a Global cluster.

what if I have multiple primary clusters and just only have one one node cluster secondary, Can GCO support this kind of configuration?

Thanks
