Yes, we have just introduced the possibility to edit effect presets, which has been a priority, because of their sheer amount. This whole logic around effect categories, types and presets with this new effect selection page, doesn't apply to input and output presets.
Normally people use three or four output presets. Volumes are not included in output presets anyhow. There is only one output section, which is global. So practically, I don't see a big inconvenience.
