I think this would be a great addition to future HubSpot updates. Like the CTA, once could be able to replace or change images as well using some mechanism. This will allow one to update the content and context on the fly, so its all replaced and updated using, say, “dynamic content module” - including, text, images, CTAs, etc. We have all been there, where content/context need to be updated due to internal requirements - only after the email was released!
I think this would be a great addition to future HubSpot updates. But, using “dynamic content module” could be a solution for adoption and ease of use.
