Hello everybody, I'm trying to find a pretty way to have a versioning system on my

graphcool-framework

stack and would have to your ideas for this. My best idea for instant is to have a clone of each model (call

${myModel}History

for example) with a relation to the up to date model (

history: [myModelHistory!]!

to have an easy way to retrieve the history of each data). In my case, I want to have a hook to deal with

${myModel}History

creation on each update (so I need the previous version of my data). If I'm referring to the doc, I can't use Subscription function (it's execute after the mutation), so my question is "can I do this history processing in a hook function?" or if you have a better idea for this use case ^^
