ACMart Hide identifying figure for double-blind review

I am writing an ACM SIG paper using the acmart class. For double-blind review we are required to remove any identifying information in our initial submission. This can be done automatically for acknowledgements and author information by simply using the anonymous option (see, e.g., this question). Sections of text can also be explicitly suppressed using the anonsuppress environment. In my case, however, what I would like is a means to hide figures that show identifying details.

Ideally, I’d like to wrap specific uses of includegraphics such that they are replaced with a box. I can almost do this by simply using the draft option, e.g.,

includegraphics[draft,width=linewidth]{figures/example_screenshot.png}

which replaces the figure with a box of the same dimensions as the image. However:

1. I need to manually add/remove the draft option, rather than it being conditional on the document’s anonymous setting; and
2. The box contains the filename of the hidden image, whereas I’d prefer it to say something like "Image hidden for double-blind review" so that reviewers didn’t think I’d simply stuffed up my submission.

Can anyone tell me if a way to do this exists already, or suggest a macro to achieve this?
