Exchange Online : No Hybrid: AADSync to Office 365 Enterprise

Hello, I am working to separate a number of users out of the Default Global Address List and Into a dedicated address list. My thought was to simply (lol) remove the users from all address lists with the Set-Addresslist -Recipient filter MemberOfGroup. Unfortunately when I got to the Default Address book I realized there was no obvious way to edit the filter. 

So my current approach is to create new address lists, new global address list and such then apply (every time I get new users). Unfortunately this adds complexity to the solution that I feel should be avoidable. If this were on premise I would go Edit AD and then change the address list: * msExchRecipientFilterFlags. Unfortunately, I am not sure if that is even possible with Office 365. (Maybe I could ask one of the support folks to Flip the switch for a miniute? )

I would like any alternative approaches to consider as well as ideas to accomplish the below two Items:

1.  Modify the Default Global Address Recipient Filter, or Change The Default Global Address List to a new one that I create.

2.  Apply Addressbook Policy as default. Meaning, I would not be required to specify an address book policy for new users provisioned.

Commands Attempted.
Set-GlobalAddresslist -Identity (\Default Global Address List) -RecipientFilter {((MemberOfGroup -ne 'CN=XXXXX,OU=XXXXX,OU=XXXXX,DC=XXXXX,DC=XXXXX,DC=XXXXX,DC=XXXXX') -and (Alias -ne '$null' -and ObjectClass -eq 'user' -or ObjectClass -eq'contact' -or ObjectClass -eq 'msExchSystemMailbox' -or ObjectClass -eq 'msExchDynamicDistributionList' -or ObjectClass -eq 'group' -or ObjectClass -eq 'publicFolder'))}

Set-GlobalAddresslist -identity "Default Global Address list" -isDefaultGlobalAddressList $FALSE

Thanks in advance for any further tho

Showinaddress book doesn't look to be sync'd with AAD Sync. Also the

Addressmembership property for the user objects do not look to be writeable with the set-address Command...

I don't think it's possible. Every solution that will work in EO requires you to 'manually' assign the ABP after mailbox creation, so pretty much what you are already using. Open a support case, won't hurt :)
