Hi @JSharman,
For filtering a dashboard or visual, you can configure the dashboard to allow users to have certain permissions and filtering control (Embedding custom Amazon Quick Sight assets into your application - Amazon Quick). Design-wise, I would recommend creating a parameter and a control on top of your filter. This way, you can have the filter be controlled by the parameter and you can have the control placed onto your dashboard for users to directly interact with what is being filtered. Moreover, to my understanding you can integrate RLS to the embedded dashboard and that should not be a problem for your use case as RLS applied on the dataset level. Refer to this link on more information on embedded analytics and RLS (1. Start Here – Embedded Analytics Overview - Developer Corner / Getting Started - Amazon Quick Community).
