I would like to be able to store files, so I could place files from home or school in one storage area to add to plans. that would allow me to access them from any location when creating plans.
You can do that now by attaching files to your plans. That option is under the planning area when you click the Edit link.
I understand that you can attach files to plans. I would like to be able to have multiple files in a common place (so I can access from anywhere). So if I am creating plans other than where my files are currently stored, I could access them to attach them to plans.
