Influencer Campaign Renders

Hey! We're hoping to try out the influencer campaigns for our event, but I'm hoping in future iterations that you could just render the images and social blurbs in advance. I get the integration with LinkedIn, but that's only one of many social platforms. Plus, not everyone will be comfortable with letting run.events access to their LinkedIn.

Also, support for PNG and JPGs would be nice. Perhaps "upload background" option that renders the uploaded file as the background automatically sized correctly.
