Incoming Mails to Local Folder

Ok, this has been asked a few times but the answers not clarifying what i am looking for or maybe i just dont get it :wink: Can be :wink:

I have 4 different Email Accounts. All are IMAP. Its getting a bit confusing with all this folders so i would like to get all incoming mails into ā€œLocal Foldersā€

I will later then add some rules to get them sorted into subfoldersā€¦
Butā€¦ how the heck do i get all the mails in ā€œLocal Foldersā€ Incoming?
