How do I avoid having to create a license every time I upload something?
When you create a license or release for the first time, there is an option at the bottom "save as default". Check that box and give it a name so you can tell it apart from other defaults. The setting you used will be saved and next time you upload something, it will automatically create the same.
You can manage your defaults by going to profilemenu-->account settings-->default license. From there, you can adjust the start date, length, and enable/disable defaults
