Allow filtering by multiple custom properties

Currently it’s only possible to filter the dashboard by one custom property at a time. It would be great to be able to filter the dashboard by multiple custom properties at once.

We want to be able to filter by a single Custom Property and then access all the custom property data for events that match that single filtered custom property. At the moment, if we filter on one custom property we cannot access all the rich Custom Property data that has been tracked for those events, and this is an issue for our reporting. It would be great if you could enable this (even if filtering on multiple custom properties takes a bit longer) - thank you!
