propagateFiltersToSubQuery example

Can someone provide an example when to use propagateFiltersToSubQuery?

`loginRecords: {`
`      sql: `${LoginRecords.count}`,`
`      type: `number`,`
`      subQuery: true,`
`    },`
`    newsfeedReactions: {`
`      sql: `${ActivityReactions.count}`,`
`      type: `number`,`
`      subQuery: true,`
`    },`
`    newsfeedComments: {`
`      sql: `${Comments.count}`,`
`      type: `number`,`
`      subQuery: true,`
`    },`

I am creating a user schema and want to include metrics from subqueries. In the example above, there are 3 tables that stores logins, reactions and comments. Each of these tables has a created_at field. How can I setup a dynamic filter so the playground shows the ability to filter the range by created_at, and have this applied automatically to all sub-queries?
