How Do I Avoid Creating Duplicate Simple Expressions? (Magic xpa 4.x)
It is easy, especially when working on very complex tasks, to end up with several expressions that are all identical. For instance, there might be four expressions that are all ‘TRUE’LOG or 0.
However, if you enter your expressions using Quick Expressions then if the expression already exists, that is the expression entry that will be used. A new entry will only be created if it does not already exist.
See How Do I Set an Expression Directly in the Task Editor? for how to enter a Quick Expression.
