Insert text into report based on field value

[fish]

I would like to insert text into a report based on a field value. For example: I want to place a merge field onto a report that is enclosed in parentheses. If that field is not filled out, I don't want the parentheses to show up. How can I insert the parentheses only when there is a value entered that field that the merge field refers to?

Why not use a text calculated field as your merge field ?

Case(fieldA = X, "("& fieldA &")",fieldA)

Case(not IsEmpty(Field), "(" & Field & ")", "")

I had thought of this, but I was hoping there would be an easier way because I have about 100 fields that I would have to do this with.
