Currently, both the funnel and the pie chart on the dashboard use the same pipelines in the dropdown, with the dropdown ID as "__BVID__9193__BV_toggle_". It would be helpful for the ability to pick a different pipeline for the funnel as compared to the pie chart. We prefer to be able to show "Sales" stages in the funnel and "Support" stages in the pie chart. Right now, changing one dropdown changes the other.

Simple tweak!
