Change source of comic (first page, second page urls)
I have encountered a webcomic  that was previously hosted on an aggregator site. With this source, only 87 pages are available, while the new webpage currently is at page 245 . I cannot seem to find a possibility to update the source of the webcomic other than creating a duplicate -- while the link to the comic can be updated, the links to first and second page, needed for scanning the comic, cannot.
1. allow changing "first page" / "second page" or
2. Add the possibility to specify an alternate source for the comic.
