Hello. Now, when you create a template to display for custom post type, no abilitty choose post of current custom post type. Bricks allow choose only page or post for preview that very uncomfortable.
I’d like to choose post from post type for which i create template.
Sorry for my English. 
This is absolutely crucial! how can you design a post template without seeing data?
I got answer from the developer:
For Content type choose Single post/page and in the Single post/page dropdown start typing in the post name of the post you want to use for the preview.
At the time of writing this ticket (January 20), there was no such thing. Apparently they added it, it’s cool!
