Is there a way to create a walking workout for the Forerunner 965?

Part of my training uses walking workouts with targeted heart rate intervals as a recovery mode.  My old 245 allowed me to create a Custom Workout that could be accessed through the Walk mode on the watch.  The 965 does not have the ability to load workouts.  Anybody have an idea for a work around?  Why did Garmin delete this feature from the walk mode.
