To all the talented modders especially Thora, please add the availability to auto rate a girl based on the perfect girl you create yourself using the sliders in Monkey mod. The ingame character editor for autorating sucks
I believe what you are asking is already there.
The sliders you modify in the Monkey personality and appearance sections modifies the game genes directly.
Assuming you have a profile, just press on the the 'gear' icon in the rating panel to update the ratings to the new values you selected. You can also press the 'evaluate' button in interpretation, which asks the game to auto-rate the model again.
Remember that the game auto rating pools many genes together, so your perfect model might not auto rate properly, because what the game thinks of a 'milky-pear' body may be different than what you like.
To somewhat counter this, you can manually set the sliders to the value you want. This has limited value as some of the genes calculation and weight are hidden - for example, you like the big breast you see but the game rate it low because the shape of the nipple or it's color doesn't match what the model wants.
There are limited ways to salvage this system without nuking it from orbit. For example the dev could expose weight tables based on the game internal calculation - so users would be able to say 'I really care about X but not Y'. I suggested this a long time ago.
While it's possible to fix this from a mod (like Q better genes), maintaining this is just not sustainable.
