custom css pier3

Hi, In Pier2 we could add a css file to the Pier tree, make settings point to it, and then during "Edit Design" we would get an editor on the contents of the file and the css would be served for the respective structure. When doing the same thing in Pier3, it seems that I cannot edit this file and that even if I have a css file with the right pointer to it, the contents are not available (when inspecting the html, "style.css" does not appear anymore). Does anyone know why is this not working, or if there is another similar mechanism in place? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
