Combined junk/trash mailbox missing on Monteray

I have just upgraded to a new macbook air and have Monteray. The mailbox list in the sidebar as an 'All Inboxes' option, but there is no 'All Junk' or 'All Trash'. Is it possible to show these in the sidebar? I know they are there in each email account but I found it really helpful to see them all in one place on my El Capitan mail
