Helix & PBS - Which channel will Helix choose when similar multiple channels exist.

[lmcnlcy00]

Hi, My mother-in-law had PBS on channel 32 (there was another, non-subscribed PBS channel at 3). When she says PBS, Helix goes to the unsubscribed channel.

Question: Is it possible to specify which PBS channel the 'PBS' keyword is assigned to?

Related question: Can you define a keyword (say 'English Soccer') to go to a specific channel? To go to a specific Helix App?

Thanks.
