Automate regular refresh/rebuild of ranks

At my last company, we automated some ranks using custom roles like outlined here: 

Shoutout to @rcochran and his team for making that happen. 

At my new company, I have a similar use case I’ll likely explore this for. 

However, the one missing piece of functionality is forcing a rebuild/refresh/recalculation of ranks. So I’d love to see this added and avoid the daily/weekly manual rebuild required with the current setup. 

Even a way to trigger a rebuild in the API would be a good solution. Since the custom role can be assigned via the API, that would allow a custom role and rank rebuild to be triggered in tandem.
