Really, there is not all that much need of them for the great majority of pharma calculations. Most of what is needed is built in and trouble getting reports to look as you like is more commonly a lack of know-how with respect to report object editing than lack of proper fields being available by default.
I don't fully agree with that. In my field of work, we perform a wide variety of tests which depend on Intersample calculations and in these cases, custom fields are a Godsend and help a lot with daily working life. The only thing is, they do require intensive validation because if you create a calculated custom field its up to you to test it against a wide variety of conditions and if anything goes wrong, it cant be blamed on a bug, its you and you alone.
