Option to Auto-Display All Initiatives from a Product Line's Child Workspaces

I would like to be able to click on my parent Product Line in the top-left navigation and immediately see a view of all initiatives from all of its child workspaces, without needing to manually adjust the filters.

Currently, I find that I often have to go into the filters and manually select the child workspaces to get a complete portfolio view. My goal is to eliminate this extra step.

It would be valuable to have the configuration option for workspace lines, to choose to show all child workspaces' initiatives automatically instead.
