Doable as a customization, but there is nothing that track the actual
iteration number on lifecycles, types, or workflow templates as they
implementing the iterated java interface, but not versioned. This means no
iteration column in the database to easily query. To do what you want, you
have to get the object identifier of the assigned template iteration and
figure out where it is in the list of total iterations. Iterations are
handled by the branching identifier and common mastered object identifier.
It's not a difficult customization, just no direct way to extract as a clean
report.
