Has anyone overcome the issue of how to show someone getting a new role at an Organization without leaving their existing role. For example, if someone is a Professor, but later they become the Department head, but don't leave their Role as Professor: you cannot just add a New Employment History with its own Start date for the Dept Head Job Title, as that creates an overlapping date with the existing role. Is there a way to reflect this change in Role without using a Compound Job Title, as the date ranges would not be accurate for the two roles
