Is there any way to add documentation to fields in my struct programmatically (after defining the struct)?

```julia
"MyStruct doc"
struct MyStruct
    "MyStruct.a doc"
    a::Float64
end
# This has docs for ?MyStruct.a

```

```julia
"MyStruct doc"
struct MyStruct
    a::Float64
end
@doc "MyStruct.a doc" MyStruct.a # Does not work

```

Thanks!
