Change category for invoices received?

[rsautosderby]

Hi
my landlord now invoices me via his quckfile to my quickfile, its set up on a recurring invoice each week for my rent.
however I noticed we set-up the category wrong his end and now there are several odd weeks showing my rent under the general column can i edit any of these? or do need to delete them all and re-invoice?

You can update category and move the data in one bulk figure through journal , no need to delete invoices
