Disable member indentation in Smart View for flex forms?

Summary:

Is it possible to disable member indentation for flex forms? If I use "Suppress Hierarchy" within the form setup, it works when opening the form, but any refreshes after that result in indented members. I also cannot change the indentation option via my Smart View settings within the context of a form (I am on 23.100).

Currently, our solution is to make all member references into Excel formulas, which removes the indentation...but is there a way to disable the indentation entirely? Or is that the only way around this?
