Yahoo Keeper Settings Inquiry

Hello all, I am switching my league to a keeper league this offseason, the decision was made last year to do so. I don’t understand Yahoo’s platform when it comes to keeper league settings. I have set the keeper deadline but I cannot find where to set the draft cost settings for each keeper. Where do I go to select the draft price for keeping a player from last year’s roster? Yahoo’s platform and setting can be confusing. Any help would be much appreciated. Thanks!
