With download templates you can save ALL of your download/production 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 by selecting the Download Template by name on step 1.
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?
