Have Baseline in Gantt View on Portfolio Level

[#1]

“For a single project, I can go to either the new or legacy Gantt and select a baseline to compare on the Gantt where we are (planned dates), and where we said we’d be (baseline dates)

I can’t do this at a Portfolio level, specifically against the “default” baseline for all projects (as there will be numerous baselines per project). I'd like to implement this, please.

This would be a powerful view that gives context visually as to how far off the mark we might be".
