Curious what situations it's recommended to use a virtual report suite versus a separate one to segment out data. And, if it's possible to combine report suites + their data together?

We're doing cleanup on our Adobe Analytics report suite/organization. There are certain evars and events that we've manually identified as no longer being in use or mapped to our tag manager. Is there an easy/automatic way to identify the evars, props, and events that are no longer receiving hits?

For adobe analytics, does the flow chart record a user journey where they browse through the site by inputting different URLs instead of clicking on a link on the page. Ex: going from reddit.com/r/AskReddit to to the homepage by inputting reddit.com instead of clicking the home page logo.
