Can we use the Links vertical for websites not owned by the client?

My client is building an Answer’s experience to act as a TEM/be the answer to Yext questions- with verticals on Answers, Listings, Pages, ETLs, Analytics and so on. We want to avoid just bouncing the user to the Yext help site any time an answer is not in the Answers experience (especially as we work with the account team to gather content). We would like to bring in the Help site information, but we already have 7 verticals so we would not be able to do a crawler without removing an existing vertical. Is it possible to set the Yext help site as the links vertical?
