Unfortunately this isn’t currently possible. I already replied in your Product Suggestions thread, which was going to be my next suggestion had you not already gone there. :slightly_smiling_face:
However, it may be possible to use third-party tools to achieve what you want. From what I read in your description, it sounds like you’ve built something like an Instagram template in Page Designer, using an Attachments field to store background images, and layering text from other fields on top. I haven’t done anything like this myself, but it may be possible to do this using something like Zapier or Integromat. For example, you could create an Integromat scenario that reads data from Airtable, builds a Google Drawings file using this data, then saves that file in your image format of choice.
