Change the Default List of fields in Task View

Hello,

Not new to the Mac, but finally got one at work. As a result, I moved from Microsoft Project to OmniPlan. My question is this. How do I set the default column/field set I see in Task View. I played around with the different included sets, but none meet my needs (and All is too much).

When I add just what I want, I see a “Custom” option, but no way to save it for future (much less set as default).

Am I just missing something?

Thanks!
