Hello @luke.dotterer​,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
If you want these admins to only have access to certain users or groups instead of the whole organization then this would not be possible. All admins have access to the security dashboard and by using the policy "Permit super admins to reset master passwords" they will also be able to reset Master Passwords. However, both of these options will apply for all the users on the business account not just a specified group.
Please let me know if this helped or if further assistance is required.
Thank you,
Henry | Customer Care
