Hi @Jen Buher - another potential solution/workaround for you is based on a setting in the SysAdmin Setup area....under Project Preferences -> Projects. "When multiple users are assigned to a task, use the schedule of the...". You can choose either 'Primary Assignment' or 'Project'. In your case, I'd suggest using 'Project'. This means:
In the scenario that you have two people assigned to the same task from different divisions, this will make the schedule revert to the project's schedule (which would be the Divison 2 schedule).
If you only need one person assigned and they are from Division 1, you can also add a Role assignment (we have one for this purpose called LT for 'Local Time')....this will force Workfront to consider it as being a multiple assignment and therefore the task schedule will revert to the project's schedule. Just make sure you edit the assigned hours to 0 for the role, under advanced assignments.
Not perfect, but it might suffice.... David Cornwell
