Hi Mike,
Thanks for posting your concern.
I am afraid that this feature is currently not supported in Google Ads API. You can only manage keyword plan at the client account level and you may refer to this
document to read more information about this.
Please follow our
blog to receive updates and new releases.
Let me know also if you have further questions.
Regards,
