Delete multiple Environment Variables at once

[luismartinez888]

Please add ability to delete multiple environment variables at once (in settings tab).

Overall managing environment variables is one of my least favorite things about blue prism. I can't help but feel like there's a better way.

Related this, it would be nice to be able to delete all unreferenced environment variables at once without the need of checking each of the variables one by one if they have references or not.

Some grouping would be nice, most variables are process specific.
