Request for "generate" button for string type and suggestion to use slug schema type instead.

Is it possible to add a “generate” button for a string type? My use case is I created a “shortID” field that I use for url-friendly unique id. I already have it as initial value but would like to generate as well

Could you use the slug schema type and name different to the page slug? At least as a stopgap workaround.

Thanks! Now that I think about, slug would actually be much better
