Gantt or Timeline View - Multiple Timeline Columns - Ability to Label by Column Name

We want to use the Gantt View (or Timeline View) to visualize and plan how our Project Managers & other site-based staff members will move between projects for the coming year - this means using multiple Timeline Columns on the board (one for each project, with the item name being the Team Member name). This would be very easy to do if only we could label the lines in the Gantt (or timeline) view by the Column Name, so we can see the project name. Currently the only options for labelling the Gantt are by item name.

Can this feature be added please?
