Link To-Do with Phase Date on Release Gaant Chart

Right now, if I move a release forward or backward, the due dates for To-Dos associated with a phase within that release do not change with the move. It would be great if these could stay in sync so assignees know when things are actually do.

The reason I say I need this in a month is if we wanted to move forward with our trial this would be a requirement of the tool otherwise it would be too much manual work to try to keep things in sync.
