Show All Archives

Currently trialing em Client (coming from Postbox) and I can’t seem to find a way to add an “All Archives” item (combined view of all accounts)? Is this missing? I found a workaround by adding Search Folder but I have 20+ email accounts (don’t ask) so this would be a lot of work to add all of them. Is there another way to add a combined archive view? Thanks.

Settings >> General >> Tick “Show Favorite folders”.

That doesn’t include all archives.
