When connecting to another Org in Azure. Can you connect to sub-domain or only the top level of the Org in question

We currently have our tenant connected to an org and wish to only connect to a sub-domain of that org. For example we are currently connected to contoso.com but we would prefer to be connected to share.contoso.com instead and maybe one other sub-domain, but if this is possible we can just create another connection.

From Add subdomains of a custom domain:

If you want to add a subdomain name such as ‘europe.contoso.com’ to your organization, you should first add and verify the root domain, such as contoso.com. The subdomain is automatically verified by Azure AD. To see that the subdomain you added is verified, refresh the domain list in the browser.

If you have already added a contoso.com domain to one Azure AD organization, you can also verify the subdomain europe.contoso.com in a different Azure AD organization. When adding the subdomain, you are prompted to add a TXT record in the DNS hosting provider.

Is your goal to have everything in one Azure AD tenant or two? As stated in the documentation and related Reddit discussion, you can set up a subdomain but you need to verify both the domains in your Azure AD.

The context of the question is in a B2B scenario. Example, we are acmeproducts.com we want to be connected to another org say coyotes.com but not the root domain. The desire is for users in cartoon.coyotes.com to be able to access packages in our tenant.
