Hello !

I built a gantt project with starting date and due date in the same column (through the due date)

It is displayed like below:

If I do a copy/paste, it looks like 24/06/2021 → 25/06/2021

I would like to increment the whole range (not the dates) by let’s say 10 days.

I already checked dozens of posts relating to incrementing dates, but not dates range. I tried the formula And I also tried all my Excel formulas to try to manually increment these dates but it does not work.

Does anyone has a solution?

Thank you :smiling_face_with_halo:
