When you use Data Driven testing, with links to external data sources (Excel files, CSV, databases, SQL) it's hard to maintain an overview of which external data sources are used, if the paths to them are correct, etc.
Would be nice if you could define, a new project item: "External data sources". (same as for example Network Suite), and within External Data sources define your data sources (same as currently with Hosts, Jobs and Tasks in Network Suite).
It would look something like this:
If possible include a check on integrity on the links (verify if links to sources are still correct, update all links etc).
