Hi I have a 4 roles defined for each project's Sheet Summary and each role can be defined with one person in it.   The 20 tasks within a project are always assigned to someone in the corresponding role.
So, i am trying to have each task's Assigned To field to take on the value of the roles on the Sheet Summary so as soon as a person is manually assigned to a role, the task's Assigned To field will be updated accordingly and other automation run depending on that value (like chaser and notification) - no need immediately trigger any workflow.
However, i cannot seem to be able to find any way of using formula to reference Sheet Summary fields.  Please help or point me to any workaround.  Many thanks in advance.
