Group by function

Hi, I'm not sure if these are already features in zzTakeoff, but I have my takeoff sections grouped by building and was wondering if the takeoff sidebar can follow the same grouping. At the moment, the sidebar only seems to show grouping when the takeoff item itself is grouped, and I can only see the grouped sections once I open the report. Also, is there a way for the batch show/hide (just like dragging the mouse down the eye icons in the takeoff sidebar) to work in the report as well, so the selected takeoffs are shown or hidden on the plans at the same time? Both would make it much easier to navigate and check quantities on multi-building jobs. If either is already possible, could you let me know how to do it?
