Hi @Thomas Delissen, in this case you should be able to filter them as metrics. This is a bit of a semantic point, but facts are usually added in insights once they’ve undergone some aggregation - the simplest of which is SUM - so they are technically metrics, albeit very simple ones. So while you can’t filter by an isolated fact, you can utilize some filtering to their resulting metric values. I tried to illustrate the process on the screenshots below, take a look 🙂
