Is there any way to change this or add another category for sales over a 365 day period?

Thanks, Roger

Is this the summary on the main admin page?
Have you tried the stats page. You can fine tune many filters there to get a plethora of info back.
Sorry, I don't think I've used the word plethora in years and it just popped in my head, so there must be a reason I used it.

ORDERS ADMIN > ORDER STATS on your drop down menu.
