Feature Request: WP Smush exlude attachments uploaded to post type

I like the newly added feature in Smush to include directories that are outside of the WordPress framework.

Feature Request:

To be able to exclude images from WP Smush that are attached to a specific post_type (and/or custom post type)

When would this be useful?

If a company wanted to offer their wholesale customers an ‘image bank’ of products but the images had to be Hi-Res, good quality etc
