View subitem updates

Right now, any updates posted on subitems are not reflect in the activity part of a board (viewable in the upper right). They also can’t be seen by adding the updates section a dashboard. The only way to see a list of all updates in subitems is by clicking on each parent item individually. This is very cumbersome, as some boards may have 10 parent items and each of those may have 20 subitems.
