Can I change the timescale in the program schedule view of Portfolio for Jira?

[Lilly Flamm]

I'm in the Schedule view of a program and the timescale seems to vary based on the duration of initiatives in the selected plan(s).  Sometimes it's by year, others, it's by 4 month increments.  Is there a way to display the schedule by month?  I don't see any options besides zooming 1x, 2x, or 3x.
