Entproto custom message type

[MarcosBustamante]

Hi,

my project is using a Json that is not currently supported by entproto in the gen process.

My idea was to build a custom proto message in a separated proto file and import this file generated file in order to use something more type safe. The final ent code would looks like this:

field.
	JSON("costs", map[string]interface{}{}).
	Optional().
	Comment(`
		This includes brokerage fees, stock exchange fees and taxes. The costs 
		should be divided by 100 to get the real value, e.g. 1000 means R$ 10,00.
	`).
	Annotations(entproto.Field(
		2, 
		entproto.Type(descriptorpb.FieldDescriptorProto_TYPE_MESSAGE),
		entproto.TypeName("Cost"),
	)),

lets say that my proto file that defines the Cost type is named cost.proto. How can I import cost.proto in the auto gen file in order to enable the type cost.Cost message to be recognized by the protoc command?

Thanks
