Currently the withHost filter only applies to Host flow queries and withApplication only applies to Application queries. It would be helpful to allow these filters on any query so one could have a panel that shows host traffic filtered by application.

There is a potential customer request for the ability to have a dashboard where two IPs can be entered and all panels filtered down to show just traffic between those two nodes. This could be achieved if there was a way for a conversations() query to specify one or two hosts. If one host is provided, it returns all conversations where the host is src or dst. If two hosts are provided, it returns only the conversations between the two, regardless which is src and which is dst.
