Hi. First of all I want to say how much I love Bricks. It’s so much faster than all the other solutions and gives me the freedom to build much more complex stuff, with much less custom code. Love it when I don’t have to reinvent the wheel. 
However, there is one feature missing that is driving me nuts. The ability to get metadata and attributes from ACF relationship and taxonomy fields. There are dozens of cases where I need some value from a related object but have to use a custom PHP function to get it.
The filters functionality of dynamic data looks like the perfect match for such a feature.
Let me give an example:
Let’s say we have a CPT Person and a CPT Department. The Person CPT gets a ACF relationship/post object field which references to a Department post.
Currently I wouldn’t be able to access any metadata from the referenced department.
Something like that would be awesome: (context: Person)
{acf_department:meta whatever_field_on_department}
