A Method to Increase the # of Trusted Domains Beyond the 20,000 row limit

There are MILLIONS of domains. We are attempting to streamline our trusted domain list across all our company applications and our exemption request process so approvers only have to approve domains once for all applications, domains are assess and approve consistently and build automations to add approved domains to the safe share sheet.
Because Smartsheet is a bit backwards and requires that we list every top level domain AND sub domains we deem safe to share and collaborate with instead of listing the handful of domains to block, our initial baseline domain list is ~35,000, exceeding the 20,000 row limit for a sheet. This list will only grow as requests come in for domains to be added.
We need a method to integrate more than 20,000 domains. Whether that is linking multiple sheets, pulling approved domains off multiple columns within a sheet or changing the entire safe share domain process so we only have to list blocked domains.
