On the Assemblies > Crew Tab you are stuck having the project's default work day hours under "regular". It would be nice if you could zero these out and replace them fully with OT or DT instead of adding them as supplemental. This is helpful when pricing night work which is 100% OT. Currently the workaround is to change the "regular" wage rate to the OT rate, but this is kind of messy and could be potentially confusing to some users.
