Does "mmColorTarget" or similar exist for Natron?

I am a VFX artist. I use Nuke for work.
Trying to use Natron for personal work.
Hoping something like the Nuke mmColorTarget gizmo exists for Natron? It matches HDRIs to a source image using a Macbeth chart. I don’t see anything obvious on the github plugins pages. I have pasted the link to the Nuke gizmo below.
Does anyone know if this exists for Natron (or have suggestion for alternative workflow)?
Also, if I am not posting in the correct place, please feel free to redirect/orient me.
