ability to mass recode one entire block to another code

it would be amazing to be able to recode an entire block code to another code. for example if i have 30 invoices coded to personal expenses sundry, it would be nice to be able to mass recode all 30 to another code instead of going one by one to each transaction to recode. alot of people say journal but journal does not look good as it doesnt move the itemized detail of each transaction
