Every job is tied to a single source folder, but you can then select which of its subfolders to include or exclude (Backup Settings > Backup What). So if your multiple folders share a parent folder, you can set that one as your source and then narrow down the backup to just the folders you want.
There's no way to collect random folders into a single backup job and there are no plans to support this type of setup.
