Feature Request: Add option to use the featured image of the post as profile image when publishing a podcast

[Ainali]

What

When publishing a podcast in a way that Mastodon picks up the audio file and makes it playable directly on Mastodon, the image of the author is used as the image for the audio, see example below.

The WordPress post has a featured image set, which is a cover art specifically for this episode. I would like an option to use the featured image instead of the author image.

Why

It would be great for podcasts with unique artwork for each episode to draw more attention to the content of the podcast rather than who was the author of the post on WordPress. (Idea sparked from this conversation.)

How

I imagine a simple toggle under the Fediverse dropdown on the post where this can be enabled (but it could also be a general setting rather than per post, I don't mind either).
