I have multiple profiles added on my Portal TV.
When it powers on I have to select a profile each time, unfortunately, this seems to be one of the only things the portal cannot do via voice command and so is the only reason I need to hunt for the remote.
Ideally, it could be added as a voice command to select a specific profile, but if not, allowing the option to select a primary profile that will auto-login each time would be the next best thing.
