Last N hours Bandwidth Utilization - plot poll interfall changing from 1 hour to 15 minutes?

I use a lot of " Last N hours Bandwidth Utilization" in custom dashboards to show the last few hours of bandwidth. But in the new opmanager version these graphs are now showing only polls of 1 hour.
In a graph of 2 hours that only shows 2 poll point which make these graphs useless to us.

Is there a way to change the number of polls (not the period) shown in the graph?
