Feature - Attach additional params in subscribe method for channel auth

[ChrisZieba]

Is there a way to send additional info to channelAuthorization on subscribe? For example, something like this where data could be passed to the channelAuthorization endpoint?

pusher.subscribe(channelName, data)

I know channelAuthorization has a paramsHandler but the issue I have is this function should return different data based on the channel.

My current hack is to create a separate instance of pusher everytime I subscribe to a channel, or modify the function paramsHandler before calling subscribe. Using the channel name to add this data won't work because of the length limitation.
