Core data accessor and KVC

Hi !

suppose i have an entity Email, with an attributed "sender" of type string. sender is the email address like "email@hidden". is it possible to run a fetch request with a predicate like : @"sender.lowercaseString IN %@",aListOfEmailAddresses ? i would like to get all emails object where sender, as a lower case string, in is a list of addresses.

i'm surprised to be able to use valueForKeyPath:@"lowercaseString" on an NSArray of NSString, but not being able to do the same thing with core data.

must i implement an accessor like "lowercasedSender" in my Email entity class ??

it could be damn useful...

thanks
