Replace images option from Uploads

An option to replace images from uploads in Adobe Express would be helpful instead of constantly having to re-upload files. What is the purpose of the uploads folder? I know I can choose images directly from the uploads folder in "your stuff" to place in templates/layouts, but it is not the same as replace where I don't have to reformat or re-add animation every time. I work for a company that has many products (thousands). I am always repurposing templates/layouts for multiple products & ones that I have used images of in the past. I feel this option could be a necessity to help speed up my content creation & get things prepared & marketed faster. 

On another note, also would love an option for Image/Graphic Shadows.
