I would like in a project plan add text to highlight cells

Hi !

I would like in a project plan be able to highlight cell from start and stop date plus decide a text in each cell that is high light.
See below how I would like it to work
I have attached excel sheet where Task 1 and Task 2 is green highlight and task 3 blue marked.

I would like to add text to the cells that is highlight from cell D so it copy out my resource name in the highlight cells

Is it possible if Yes can some one help me ?
