Auto-populate date field with min-offset day?

I have a date picker field for “Desired delivery” that I’ve set with a minimum offset of 7 days. However, the following day is automatically put in this field, so if the customer skims by it and doesn’t select a date, they get an error message asking them to pick a valid date.

Is there a way I can have this field automatically populated with the offset day instead of tomorrow’s date so that people aren’t constantly getting errors when they don’t pick a date?

Thanks for this amazing plugin!
