I think a custom field is probably the best way to accomplish this. If
you're adding the field on a project form, this would be the formula:
IF(Alignment>=45,">=45","<45") Then you can set up grouping by that
field. If you don't already have it set up, I'd recommend having a
"Admin Use" form onto all templates. That way, when you have a reporting
field like this one, you can pop it into the admin form and it already
exists on all jobs, so it's just a matter of recalculating the
expressions.
