This idea has been merged into another idea. To comment or vote on this idea, please visit WEBFLOW-I-303 Ability to add images to the CMS from the Asset Manager.
Currently when attempting to update an existing image in a CMS item, it's providing an upload input where we need to re-upload assets to use them in the CMS. This limitation doesn't allow using existing Assets that have already been uploaded.
We should be able to just select images from existing Assets!
