Current software has this, and it saves a tremendous amount of time.
If there is a multi-family project or a hotel, all with multiple of the same units, can you "surround" the take-off on the enlarged unit plan, then simply count how many units there are, so everything in the "surround" gets multiplied by the number of counts?
For this example, there is 4 UNIT A1's, so I simply surround the enlarged takeoff, and count 4. Sometimes there are multifamily projects with dozens of similar units, so it saves a lot of time.
