Syncing Historical Subscription Revenue Data with Group Profiles

Hello! I'm attempting to sync historical subscription revenue data with the relevant group profiles, and plan on keeping it up to date with warehouse make group properties historical, even using mirror mode. I'm specifying the appropriate $time field as well, as I assume this would be required, but the documentation isn't clear about what is actually needed. Am I missing something obvious here? Right now my goal would be to use the SasS Company KPIS template, but the properties aren't available for me to select, see screenshot
