It would be absolutely marvellous if the ability to use a field as the replace value could be incorporated into the Regex tool. Currently the "Replacement Text" field is a hardcoded text value, and so to make that dynamic you have to wrap the tool in a batch and feed in the value as a Control Parameter. If we could just select a field to use as the replacement value, that would be spiffy.
