Dependencies hiddenin Timeline View with grouping

Hello fellow Coda-ers,

As i didnt find a way to do this or a solution

Im building a timeline which is grouped by:
Department
Workblock
User Story

There are many interdepartmental dependencies between user stories and even workblocks
which i would like to visualize. Unfortunately, as soon as the groups are collapsed, the dependencies lines are not visible anymore.

Would it be possible to keep the dependency lines visible and stay connected on the workblock and if that collapsed, stay connected to the Department?

Thanks!
