Choosing main cluster before resolve

[EdenAnteby]

Hey

In my use case, I need the main cluster value to be the longest mentioned value in the cluster.
I've checked the output of my doc._.coref_clusters:

Medable: [Medable, Medable],
Gond: [Medable CEO and co-founder Michelle Gond, Gond]]

I've tried to set the value of:
doc._.coref_clusters[1].mentions[1]._.coref_cluster.main = MyChosenString
and then calling doc._.coref_resolved again, but no luck.

Is it something I can control? Should I just create my own 'coref_resolved' method based on the clusters?
Thanks
