Just on a basic level, my Assigned to column at times has multiple names - I have enabled multiple contacts.
The issue comes when I collate metrics (summing them) in another sheet where I am pulling numbers based on who the task was assigned to.
So, lets say I have Jack and Jill while their values would collate, if a task was assigned to both Jack and Jill, it would not collate their hours for both of them but just detect it as a whole different entity
I presume one workaround I could have is to actually collate Jack and Jill in my other sheet and just add the value to their respective sums
