Set object name in grasshopper

hello,
my grasshopper script generate surfaces, and i want to name them by letter un number, like C1, C2, C3…
i tried with a python script in gh, but it don’t want it… is there a easier way?

Several plugins have this capability. Human, Elefront are very popular.

This is a typical workflow in Elefront, grafting and tree alignments being critical.
