If you set repeat clients only can you still recieve messages from pending and archieved clients?

I want to set my availability to repeat clients only but I am pending with two, hopefully, future clients and I don't want to block their messages. Also, if I have to say no to prospective clients because I don't have the availability I always tell them to keep me in mind if their new sitter ever cancels or they need me for vacations or anything like that so I don't want to block those messages from coming in. Thanks for reading, I appreciate all the help I can get lol!
