lists and/or promoted sources in a dashboard

Hello all,

Two semi-questions: 

1. Can I use a promoted source code as a filter in a dashboard? These source filters I see appear to be line item or order filters, but I was hoping to filter the dashboard to everyone who was promoted with a specific source.

2. I'm struggling with using lists to filter dashboards as well. I have the Analytics box checked on the specific lists in question, and our backup was at 1am today, so the lists should be available in Analytics. I'm also using the list as filter in a widget with the list number surrounded by commas.

What am I missing?

Thanks,
Lesley
