That is not possible. The library screen is not set up to be used like a reusable component that I can just throw into a UI for a different purpose. Also, the reason it's set up that way is you are not selecting a song - you are selecting a specific file. Songs can have multiple files in them, so the UI lets you pick which of those files to add. The feature is fairly limited right now, and you can't select a range of pages to add from an existing file in the library. It's just meant to be a way to merge PDFs. I'll expand the feature more in the future, but I needed to see if it was even something users would make use of before spending even more time developing it. One minor enhancement I'll probably look into adding sooner is respecting the page order for the file that was selected, so that the entire PDF isn't added (which would make it unusable with large PDFs imported through csv files). Another thing I may consider is switching the UI to show songs more like the "Find Song" dialog which is similar to the library screen in appearance, but if the song has multiple files under it, I would then have to pop up another dialog asking the user which of those files should be selected. This just gets messy because the UI currently lets you selected multiple files at once, which is nice, but if I have to pop up a dialog like that, the information for which file was selected would be hidden from the user, as the library style UI doesn't show file information. Or perhaps I change the dialog to only allow the selection of a single song/file, and the user would just have to load it multiple times to select multiple files, as it seems unlikely that a user would be doing that anyways.
