Impersonation settings in ATP anti-phishing policies

We are a large government agency and have more than 60 users to protect from being impersonated as message senders.   https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/set...

We had a similar case opened with MSFT and the engineer said that we can create more than one anti-phishing impersonation protection policy since we have more than the limit of 60. This feature was one of the key drivers in pursuing O365 ATP P2. So, all the stuff we have been told was false and we now we have a product that can't help us. Why? Why? Why? There must be others too...

    The limit is now 350 users per policy. We had more than 1000 executive addresses in protect list and we had to create multiple policy with different user scope to apply them.
