XPage view - problem with nested categories in single column

I have a Notes view where the first column shows nested categories by separating values with backslashes.E.g. If the value of the first column for one document is “Bugs\Formula”, the Notes client shows something like this:

I’m trying to get the same functionality in an XPage view, but there’s one annoying problem: nested categories are shown with the same indent level as the parent category. Here’s a pic of the XPage version of the Notes view. “Formula”, “LotusScript” and “Profile Documents” clearly have the same indent level as the parent category “Bugs”, when they should be indented further:

Is there any way to make the indenting match the Notes client?

Subject: re nested categories

depends what you’re trying to do

filtering view content based on “category\subcategory” notation is broken in the Java API, and we depend on that for XPages. We are trying to address this for 8.5.1

If you have two separate categorized columns and you simply want to align the main category as the first column and the sub cats as the next columns, then I have done that.

Probably best if you could make you db available with some sample data so I can take a look.
