URL with String wildcard for Dashboard with Filter

Here is an example URL for a dashboard with a filter:
http://metabase.SomeURL.net:3000/dashboard/17?category=USD

I would like to be able to find results for USD% where % is a wildcard. This would find all results where category begins with USD…

Is there a URL character that would act as a wildcard for a filter on a string value?

Thanks for considering!

No, you need to embed the dashboard in a web page and pass the filter value using the SDK.
Here's mine:

It takes the values from those drop downs to specify which dashboard, the refresh rate and sets the Team (offices-group-team is a hierarchy, only Team is set).
