In the app.use cors origin array is it possible to use a wildcard for subdomains? For example, we have many sites like A.wave7.cloud, B.wave7.cloud, C.wave7.cloud, etc that are all on the domain wave7.cloud. Can we use a wildcard like *.wave7.cloud or maybe just use the main domain name of wave7.cloud instead of putting every individual subdomain in the array?
