not without a pri tie between tenants, if you allow ten to ten, it's a system prompt. if you have to do that, build a pri to pri interface between tennets, then add cdp/dsc's with a frl high enough to allow just those dn's to the remote tennant. the package you listed might do that, but without it, i've done it by using a dual pri, one trunk group for each tenant.
