How to customize navigation in Obsidian Publishing

I have folders with, for example, the following structure:

848
848-01
848-02
848-03
……

However, when such folders are published with Obsidian Publishing, file 848, for example, is for some reason placed last among the files in that folder, and because of this bug I am unable to customize the navigation to bring it back to the head of the folder. In the absence of any indication when this bug might be fixed, is there any way to achieve the same result, preferably without changing the file name?
