Suggesting Ability to Connect Workfront Planning Records to Tasks

My organization uses Workfront Planning to manage our Enterprise Strategic Plan. Through the use of structured taxonomies, we’re able to create a timeline view that allows for the breakdown Strategic Theme -> Strategic Sub-Theme -> Strategic Statements -> Projects, showing where each project falls on the timeline that impacts its associated strategy.

We'd like to break it down a step further and be able to expand each Project associated with a Strategic Statement within that timeline view to show the Milestones within the Project, or specifically labeled Parent Tasks, allowing teams to view where each phase of any given Initiative then falls within the overall project timeline all in one view.

Currently we're unable to do so as the only available Workfront Object Types to connect to in Planning are Project, Portfolio, Program, Company, Group and Original Request.
