Color Curves override doesn't blend smoothly between volumes

Unity: HD RP

HDRP

2022.2.X

2021.2.X

The curves parameter cannot be blended; if we want to add a texturecurves interpolation it is more a feature request

Steps to reproduce:

1) Open attached project

2) Move camera outside of a local box volume

3) Notice how Color Curve override doesn't blend smoothly

If there's a technical limitation on interpolating between TextureCurve this is still a legit UX issue.
