Auto Rift->Greater Rifts bot

[zerorelativity]

Basically I'm wondering if its possible to have a bot idle at trial greater rifts, and obtain a level 1 key, Then use the key to enter greater rifts until it fails. It will do this until it runs out of greater rift trial keys. Then it will run normal rifts for another key. After it runs out of normal rift keys it will do bounties for rift keys and then repeat the process.
