That's what the Enterprise level is for — it's built for large complexes and property management groups running several properties, and it's scoped to what you actually need rather than sold as a fixed bundle. The levels are priced against how many residents you expect to reach rather than how many buildings you have, so a handful of small properties and one large complex can sit under the same plan.
Two things make a portfolio easier than it sounds. Unlimited virtual events come with every level, so a trivia night, a magic show or a murder mystery can run at each property instead of being rationed between them. And in-person coverage already reaches the Bay Area, Boston, Chicago, New York City, Philadelphia, Seattle, Southern California and Washington DC, so buildings in those markets can have a chef in the clubhouse while the rest run virtually. Give your account manager the community sizes and the cities you manage, and the plan gets built around the mix rather than around your biggest building.
