Most other MDMs have a feature to edit a plist after it's been added. So this request is two-fold:
  1. Make it easier to edit/remove an existing plist file
  2. add a section to add extra things into a plist file (e.g. Impero requires that you add custom lines to your plist file and shows you how to do this in an MDM with a specific section for that. With Lightspeed you have to manually edit the file before uploading)
