Folder Group in Legend

Is there a way to "Group" takeoffs on the legend just as in the side bar?

Also, back in OST there was an option to select if we wanted the legend to be grouped or not (nothing related with what I mention above). This option was to have an option to consider the legend as 1 only item or different items per row. I found this like a nice option that can give us more freedom to configure legends and locate them appropiately in each page (most of all when we have too many takeoffs on the same page).

Thanks on advance.
