I understand it cannot be done easily, I expected it to be honest.
But I am not sure why you seem so surprised.
If I search AW there can literally be dozens of girls I might want to see, even after screening their profiles by price services etc to filter out those who aren't my cup of tea.
My guess is that it would be harder and would take much longer to find 3-4 with good reviews and who meet my standards from these dozens, than from a list of, say, the top 20 best reviewed girls of the last year.
I appreciate this might not work for everyone. Anyway, not trying to convince anyone of anything, you asked why I wanted to do it and I answered.
I appreciate it's all a moot point anyway if technically it cannot be done
