For AE to be truly useful to an integrated branding approach, being able to upload existing PDF's and convert them to Express templates would be VERY helpful. Or upload IDML files. I am puzzled why we have to reinvent the wheel by creating assets within AE when we have the Creative Suite to generate files? This is easily done in Canva with remarkable results. I would think that the SHARE feature could have the addition of "Share to Adobe Express" and go directly into the brand. Or, have a feature within the Libraries that can upload to Express. This would be a game changer in creating branded assets in AE. For now, we are stuck with your competitor for this feature.
