That would be ideal.  I do not want to re-type all my tasks if they are already in ms project or excel for that matter? Most apps allow an export to csv too so would be great to import from csv. 

What about making one project a sub-project of another? I have a master project that is made up of 10 sub-projects being completed by others, I would love to be able to have those dates and tasks fill in my master project plan.
