Programming a plugin for Davinci itself

Hey, does anyone know if this is possible? I tend to grade all footage from one camera in one scene on a timeline and Davinci can't seem to figure out how to copy/paste from a timeline to the final clips in this instance. It should be easily done, just store the node hierarchy in an object of objects then paste all the details into the target clip's node.

So I was thinking of making a plugin so the right-click menu had an additional option in the node area of

Copy Node Tree

etc.
