Different custom messages for different stages of review in Workfront Proof

[#1]

Within automated workflow it would be really beneficial for us to have different custom messages for different stages of review.

For example: Stage 1 goes to these people, they get this message. Stage 2 goes to these people, they get a slightly different message... etc etc

We have a range of different stakeholders that need to see proofs for very different reasons and often information we are sharing with one group is confidential from other groups.
