FF dependecy to push Finish Date, while holding Start Date

Let's say I have two activities, A & B.

A has a Start of 3/1/2016 and did indeed start on 3/1. However, it cannot finish until B finishes. So we put down B as a predecessor to A with a FF dependency.

The problem I'm seeing is that as B Finish Date gets moved around, the Finish Date for A also moves, which is great; but the Start Date for A also moves. It seems that Smartsheet holds the duration constant. Any way to anchor the Start Date for an activity instead?

If not, does anyone have any workarounds, other than remembering to go back to A and manually changing the Start Date back?

Hello Anthony,

You're correct in that the duration of a task is held constant when changing a start or end date; however, you might consider making the task you wish to lock dependent on a milestone (this appears as a diamond in the Gantt chart). This should keep the task's start date constant if the end date is changed.
