New Timeline - date/time fields no longer default date

We’ve have some timeline activity types with required start and end date/time fields in order to sync over to SFDC. Previously, the fields used to default a date/time when you created the timeline entry but now users have to scroll through each field (month, date, year, hour, min) to log this - a lot more clicks. I poked around but could find a way on the admin side to set a default. Anyone way to default the date in there?
