Cannot Add Multiple Twitter oauth keys in index.js

[sprabs]

In the index.js file on parse-server, I have a setup like this (hosted on AWS EB):

oauth: {
facebook: {
appIds: process.env.FACEBOOK_APP_ID
},
twitter: {
consumer_key: process.env.TWITTER_CONSUMER_KEY,
consumer_secret: process.env.TWITTER_SECRET_KEY
}
}

We currently use different Twitter keys for our iOS and Android clients. What's the best way to add both sets of keys?
