Good morning Bianca,
I originally setup an overview board that captures pertinent dates for various stages in our processes. I learned through piloting, that the dates (Timeline) from the individual project board, will aggregate the dates of that column in the overview board. These were setup using the connect and mirror functionality. So if we had the install dates being say 2/24 - 2/26, the apps dates from 3/1 to 3/3, it would show them as 2/24 to 3/3 in each column i mirrored, when i really want to show those two date ranges individually in two different columns on the same row of the overview board.
The dashboard question was something i found in the community but couldn’t find documentation on what they posted. I think i am using the dashboard type correctly, so nevermind on that.
