Is it possible to create Permissive dict with dynamic amount of keys but have Enum values? I'm trying to create a dtype config, for example:

solids:
  solid_a:
     config:
       dtype:
         col_a: type_option_a
  solid_b:
     config:
        dtype:
          col_b: type_option_a
          col_c: type_option_b

not with the set of config type we currently have
