Is is possible to pass query parameters to SAP BOE Dashboard through URL?

I have used Open document API for accessing Crystal reports through URL.

We can pass certain query parameter values appended in the URL and the report query filters the data accordingly.

Is it possible to to something similar in a dashboard?

For e.g. I have 750 dealers but I need to have a single dashboard for all where in I can pass the dealer code to the dashboard and then the dashboard displays the filtered data on it.
