To have multiple data driven ads is possible with Hype Data Magic but the idea is hindered somewhat because of the disability to deselect files. This is a long standing bug (feature request). Last time I checked it was still there.
Apart of that you can just create and ad an replace asset in the exported version (resource folder). Text content can be replaced in the JS file, but that wouldn’t be directly visual. You could preview it in the browser, though.
