OK, so there's no way of adding the desired or amended css styles to Data Assist so that it does create the correct style sheet for me each time. I've created my own DA preset, but I can't see a way of editing CSS in DA other than for buttons.
The form creator allows me to create very styled forms with customised CSS that can be saved as a preset, but DA doesn't seem to have the same ability... or does it?
Thanks
Mat
