Can I Upload Partial SDFs for Campaign Optimizations in DV360?

Hi everyone! I couldn't locate any information about this on the DV360 support page. I'd like to streamline some typical optimizations in my campaigns using SDFs and am wondering if it's possible to upload them with just a few specific columns rather than all of them. This would help to simplify the view and ensure that I don't accidentally remove information I need. Is it feasible? Maybe there are some columns that are mandatory, but not all of them. Thanks for your help!
