Require the Linkage of Enhancement based on customfield

[Kevin Dalton]

We have the logic to for the requirement of the linked field to a certain project if it is linked before the transition occurs.  If the linkage is added during the transition the script does not pick up the fact that the link is added to the screen.  Is this possible to add?
