[Idea] change data_sorces based on some conditions 

I'm using Blazer along with `Hypershield`, I have two `data_sources` in my `blazer.yml`, and I would like to keep both, however, I want to either just show `Hypershield` data_source or both data_sources (`Hypershield` and `Database`) based on my user class

I was trying to use the before_action_method to do this, but I wasn't successful, is there any workaround that can allow me to do so?
