Tensorboard Reward Distinction between Extrinsic and Intrinsic Rewards

I think it is a bit annoying to write my own function to plot the extrinsic rewards myself, when using ICM. 
It would be great if this was an in-built feature, where one could directly see the extrinsic and intrinsic rewards separately in tensorboard for better comparison, and maybe even separating the different (extrinsic) rewards rather than just seeing the cumulative reward.
