I'm working on a custom scheduling application wherein I'm trying to open a gantt view to a particular date from a calendar view via a method executed from a button in the calendar popup.  The idea being that you select a date in the future and it opens a gantt view to that date to view availability.  However, the default behavior of the gantt rendering is to open to today's date even when context is passed setting a different start date.  I've looked through the available gantt attributes and there doesn't seem to be one to modify the date that it opens to.  Has anyone achieved this strictly via XML or Python, or is custom JS going to be needed?

Thanks in advance!
