Feature Request: Pick multiple values in filter component

Feature request

Is your feature request related to a problem?

When picking a value in a filter component, say a cohort, you can only pick one, then have to open a new one for every other value you want to pick.

Describe the solution you'd like

Support picking multiple values in the same filter dropdown, so it doesn't close until I pick as many as I need then save it, then have it add as many filters/breakdowns as I pick within the supported limits.

Describe alternatives you've considered

• Use it as usual one at a time

Start by locating the analytics filter component described in the request and trace how a selected value is saved and rendered as a filter or breakdown. Implement multi-selection that keeps the dropdown open until saving, respects supported limits, and adds each selected value; verify the resulting filters in the analytics interface.
