Mass updates for roles in Home for Unite

We just implemented Unite into our system and in order for users to see Unite in their Manage account, I have to manually add the permissions for the Unite role to each user and also each company inside of Unite. I would like for there to be a way to just assign the Help Desk or Finance role for Unite to each Home user and then have an option for All companies instead of having to drop down and select each of the M365 companies before I can click save.
