Payment for athletes

I am a coach on Intervals.icu and I’m currently a supporter. Is there a way to cover the supporter status for a fixed number of athletes (e.g., 5 slots) rather than upgrading specific individual accounts?

I’d like to pay for a bundle of slots so that whichever athletes are assigned to me don’t receive the supporter pop-ups.

David announced “coins” were coming soon, where you can “sponsor” athletes.
Not sure if this has rolled out yet.
