I plan on using ClearCase to version control our Test Cases and corresponding scripts. Once I port over these baselined scripts what can I do to maintain a version history on the TD side (haven't been able to get version control to work thus far via TD 7.6 SP2)?

Any way to tweak the overwrite option if Subject Field (of my Test Case) = Subject Field (of my Test Case) on TD? By tweaking I mean change from overwrite to 'update'
