Dashboard level multi-filter values in URL


Is it possible to provide multiple values for a dashboard level multi-filter in the page URL? I can pass it a single value using the same format as filters (URL?column::multi-filter=value) but I cannot find a way to pass more than one value.

I would like a way to share the dashboard with interesting filters already set.

The ability to have nested filters- for example selecting a state from one filtered column that would limit the options visible in a separate multi-filter for cities- and allowing multi-filters to default to select all would help me accomplish something similar, if those are easier problems to solve!

Thank you!
