Help Managing One Amazon, One Google, and TWO Home Assistant Accounts

I’m looking for best practices in the following scenario:

I have Home Assistant running in two homes, both with separate Nabu Casa accounts.

I want to be able to use Alexa and Google Home in each house to use voice to control that one home. I have one Amazon account and one Google account. Is it possible to add both services to each HA account? That worked fine with VeraPlus; I just had to keep track of what I called my devices so I wouldn’t be controlling two “Dining Room Lights” using Alexa, for example.

I tried using a second Google account in the second location, but the Google Home app said it would delete all devices (from Google Home) at the first location.

I haven’t tried adding Amazon yet. Any suggestions?

Thanks
