No drop down arrow for Bookmarks

In the Mac version of Scrivener 3, when you put a Bookmark in the Inspector and in the Quick Reference Panel, if it has any document files and/or subfolders, a drop down arrow appears on the right side of the Bookmark. Which is VERY handy for quickly referencing information. There is no drop down arrow for Bookmarks in the Windows Beta 12 version. Will this feature be added? I’ve added a Screenshot so you will know what I’m referring to.

This is a new Scrivener 3.1 feature, which is still not implemented in the Windows version. We aim for full feature parity with Mac v3.0 as much as possible, so most likely this feature will be implemented at a later stage.
