Maybe try exporting all the dashboards as ".dash" files? These can be examined/edited in any plaintext editor like Notepad++, so presumably you could do a control-F (find) for the widget types in question. The challenge would be doing this in a timely manner. If you're using Notepad++, you could try opening all of the dash files at the same time, then using the "Find All in All Opened Documents" option, but this might not be very feasible if you have a ton of dash files. Aside from that, though, I'm not sure of an expedient way to search them all quickly; worse case, you'd have to check each file individually, but if you're doing that then you might as well just open each dashboard one-by-one directly in Sisense 😛
