Toggle to prevent specific wolves from breeding

Hey all,

I was just thinking-- it'd be nice to have a way to prevent certain wolves from breeding.  I'm not proposing this as a sort of "this wolf can't breed, ever" kind of thing, but more like an option along the lines of Lioden's lock button (another feature I'd love to see hit WD tbh).  Basically, you could mark the option that says "I don't want this wolf to breed" and the wolf would not show up in the breeding menu or display the heat icon on their page (this is mostly for females, since males already are so restricted breeding wise).  I've got a big pack, and sometimes a lot of my wolves go into heat around the same time, but they're not all ones I actively want to breed every time they go into heat.  So it'd be nice to have a simple toggle to disable/enable that, just so it's easier to look through and make sure I've set up breedings for all the wolves I want to breed without getting confused by seeing the heat icon and then realizing "oh, that's just a wolf I'm not breeding this time".  It's a very small, quality of life sort of thing, but I feel it'd help make things just a little easier to keep track of.
