Lightbox time fields

Is it possible for there to be multiple time selectors for different task attributes in the lightbox? By default, there is start_date and end_date, and map_to is set to “auto”. What if I have two more dates, like planned_start_date and planned_end_date? Can this only be done using the templating?

Sorry for the double post. For anybody wondering, I found the solution here: docs.dhtmlx.com/gantt/desktop__t … properties
