Is there any existing functionality, presumably an auto materialization rule, to only materialize an asset when it is both stale and a dependent asset needs to be rematerialized? For instance, say we have an asset A that is rematerialized once per week. A has a dependency on asset Q, which is occasionally rematerialized via sensor but only rarely gets updates. Is it currently possible to set it up so that when A fires, Q is only rematerialized if it hasn't been rematerialized in the past 48 hours?

Hello 👋 I think you could do that with Auto-Materializing Assets and Freshness Policy
