Portrait Photo Curation

I got Alex like 10 times in a row today and had to stop using the tool out of frustration. Alex is a great model, but there are far too many random pictures of his back, and the back of his head and of him over all in the portrait tool(plus I hate the phone he holds). He is by far the most common model, in fact I have filled 10 pages in the suppressed image tool of exclusively him, plus 250 of my own photos uploaded, and still got Alex, by my count, 10 times in a row today. TO be clear, I do not want Alex removed, far from it, I'd just really like some curation so I'm not practicing on the same model 8/10 times everyday. I have ADHD and I really struggle to focus, and the tool has been a godsend for daily practices but every time I skip an image increases the chances of me fucking about and getting distracted.

I've tried everything I can think of to resolve the issue myself, including submitting photos of myself that I got a photographer to take to reduce his overall density, but I've ended up getting really bothered by it lately, but like I said, I'm really grateful for the tool so I don't want to take it out on you, I also have no issues with the model themselves so please don't take it that way.

Basically and politely, please remove some of the repeated or dud photo's and deduce the overall number of photo's of Alex in the portrait tool.
