In the Grid view, it would be helpful to have a Conditional Formatting option that allows carryover to Timeline view bar color. For example, a checkbox to the right of a Conditional Formatting row that states "Apply format to Timeline view bar."
Currently it is a manual process to switch back to the Gantt view, then click on individual bars and change the color one by one. Then return to the timeline view to see the color applied.
The Timeline view is a total game changer and this additional functionality would be a Level UP and save time.
