Sigil works for this

, Rename the cover (ie. map1) in the Book Browser, then you must:
1) either add your cover image before the
Map
2) Sigil split the page and set the new cover page semantics to 'cover' (Sigil does not appear to have a 'remove Semantics' ), shifting that flag.
Adding your cover in Sigil is fairly easy (Steps vary depending on Sigil 4.x or 5.x). Just select the cover source (cover.jpg) from the (calibre) books folder., then place it on the cover page.
