'Mis' Understanding of Top & Skin Printing

[PartySausage 24]

I'm putting a print together that has a couple of exposed flat surfaces at different heights. My belief was that any exposed upper surface would be printed in accordance with the top/skin settings regardless of where it appears. However the realisation dawned on me today when previewing the print that this isn't the case & only the upper most surface prints with the top/skin settings, whereas the other surfaces are printed in accordance with the top/bottom settings only.

I have different speed & flow settings for the skin wrt to top. hence would like to print those other surfaces as a skin too. It looks like the only way to do this is by changing the top settings to match the skin, however there isn't an option in Cura to set the speed & flow settings for top/bottom independently. Am I missing an easy trick here to use the skin for all surfaces or am I snookered?
