Are you able to add subfolders in the "New" folder of an asset contribution folder and still have it work as a contribution folder in the Brand Portal? We are using asset contribution folders in the Brand Portal to serve as an the upload point for assets being created for projects. But many of these projects need to have some structure to the assets they are sending. For example, we have a project for digital banners but need to organize them by the channel they serve. I was hoping to do this by adding a folder structure under the "New" folder and then have the contribution functionality handed down to the children in there. Is that doable or does every subfolder then have to be a separate contribution folder?
