Show features and master features linked with an initiative under the roll-up initiative as well

We use the roll-up initiative feature a lot at the line level and the initiatives at the product level. So all the features and master featured are linked to the initiatives but when we look at the roll-up initiatives, we are not able to see them as there is no direct link. Having the option to see the features and master features in the hierarchy of that roll-up initiatives i.e. rolling them from across initiatives that make up the roll-up initiative will give the complete feature. All that is needed is a show/hide option for child hierarchy.
