AFAIK it does not contain any function to support this directly. My primary way to interact with Archive Box for such purposes is by calling it on the command line. Scripts may be used to obtain the URLs of interest from any source. When I started with Archive Box I had some existing downloaded Websites from ScrapBook and Save Page WE already. I used some hacky scripts to extract the URLs from the respective pages and overwrite Archive Box' downloaded copies by my original copies as to make it work for pages that had been deleted in the meantime. All my data sources were local/desktop though.
