DateTime Picker defaulting only the time

I’m trying to set only the time in the picker to a default value. Right now, the value stays null until the user selects a date, but the time is defaulted to midnight. 99.99% of the item, users interacting with the component will need to look at any date with the time of 07:00:00. Eliminating the requirement to select the date AND change the time from midnight to 7 am is the goal. I’ve tried some script transforms with no success. To summarize:

Value is null until user selects a date. Once date is selected, default time is 07:00:00.

Thank you in advance.
