Filter options for Release/Sprint Dashboard

Currently, all items assigned to the release/sprint are counted in the release dashboard and considered for the item burndown chart.
In my configuration I would like to distinguish between planning elements (User Stories & Tasks) and work product elements such as requirements. The burndown diagram is intended to show the burndown of user stories or tasks.
On the right I can filter by Type (Tasks or User Story), but this filter is only applied to the item list and not to the burndown chart. Unlike filtering by teams, where the filter is applied to the list and burndown chart.
Questions:

Is there a way to apply filters to the burndown diagram? (similar to Team filter)

Is there a way to basically define a filter on relevant trackers for the release/sprint dashboard? (similar to the planning view)
