With download templates you can save ALL of your download workflow options. This includes slipsheet settings, load file preferences, naming convention, and more. To create a download template, run through a download process to save all the options you want, and then, on Step 4 of the download/production, enter a template name and click "Save as a Download Template."
The next time you run a download, you can use these same options.
To make downloads even faster, these templates can then be copied from project to project, as described in this article: How do I create a download/load file template that can be shared across my account?
