Search bookmarks across multiple opened PDF files

Is it possible to Search bookmarks across multiple opened PDF files. The reason I want to do this is that I have scanned mutiple sheet music books and set up bookmarks in each one. I know i can view bookmarks but when you have 150 plus pages a search facility would be very useful

Currently Sumatra can only search for text in the active tab/document, and it cannot search through bookmarks at all. An open request for the latter can be found here:
