Can I condition only on hand, not on body+hand?

[ChaerinMin]

Hi, thank you for your great work.
In the README, it seems like Openpose-Hand is supported and it's different from Openpose-Body+Hand.
But only a single checkpoint named "control_v11p_sd15_openpose.pth" is actually provided.
And when I set draw_body=False to condition only on hand, the model looks like it thinks of the hand skeleton as a body skeleton.
Is there any way I could condition only on hand?
Thank you so much
