How to adjust the flow ratio within a height range modifier

Hi… is there anyone out there that can help me with this issue?

I have a part with 6 height range modifiers… i need to reduce the flow ratio on 2 of the profiles that are just a single layer and print a honeycomb pattern

I can see a way to reduce if they were a solid infill but not sparse infill which this effectively is

any help would be much appreciated
