Hey is there a way to create dashboard portlets that can be added multiple times to a dashboard and have some sort of configuration?

You could make multiple deployments of one portlet and handle the differences in the script parameters.

But I can not do this dynamic correct? Like e.g. I want a widget that show Vendor Stats and I give the user the option to drag in the widget. Then select a Vendor and then it shows vendor stats for Vendor A. And later they can drag in the same widget again but this time select Vendor B etc
