How do I sort BOTH my files and bookmarks by name?

Hi, I'd like to sort both files and bookmarks in the same folder by "name", but it seems that all sorted files come first and then bookmarks come after the files, such as 01_file name > 03_file name > 02_bookmark name. I was wondering if I could sort them altogether like 01_file name > 02_bookmark name > 03_file name.
