How to restrict adding multiple Facilitators and Business Leaders in Talent Review Meeting creation

Content

Hi,

My requirement is to restrict adding multiple Facilitator's or change Business Leader while creating the Talent Review.

E.g HR US is creating talent review meeting for US population and he/she can add anyone outside US as another facilitator or change Business Leader. 

Is there anyway to restrict the Facilitator/Business Leader selection outside the creating HR's organisation, using security or AOR?

 

Thanks
Ram
