Arma Reforger Workbench opens with a window that allows you to load, scan, or create a new project. With the changes to DayZ 1.30's Workbench, a feature like this might be possible, with a few caveats to how Reforger's operates.
As of right now, a directory that contains a mod.cpp with a name parameter can be used to designate a File System in Workbench. But this requires users to have a profound understanding ahead of the time in order to manually setup a batch/powershell script to just launch Workbench with the mods you're wanting to work with. Using workbench is often overlooked due to the fact it just does not work for modding out of the box, but requires manual environment setup ahead of time. If implemented the "Scan for projects" option should support loading packed mods and unpacked/source.
