Remember fields (or prepopulate them...) without using URL params?

Hi!
For my site (a kind of youtube but just for bird videos), I need to be able to remember some fields. It's quite common to add more than one video for the same species, or taken at the same day, same locality... so if that fields can be filled with the last values, that would be great. The user can remove them, or modify if the video was taken a day before.
Is there any option to do this with this module? What I was thinking of was to store all the node fields while the registered user clicks on Submit, and once the user goes again to node/add/video the fields get prepopulated.
What would be the best option for doing that?
Thanks!
