How can I pass arguments to an Operator inside a Macro Operator?

Question

I´m using a Macro type Operator to concatenate actions which require the user to interact at some points, so I create a Macro Operator class and then populate it with some existing (or custom) Operators, using the define method.

Then I call it from the user interface like some regular operator, except that, (I suppose) I cannot use the user interface to pass arguments to a specific operator inside the Macro, so I want to know which is the right procedure to pass these arguments, because I need the operators to react with different settings than defaults.

I tried to add more arguments to the "define" method during register, but an error is raised declaring that it can only take 2 positional arguments: the idname of the Operator (and I suppose self).

import bpy

class Panel(bpy.types.Panel):
    bl_label = "Panel"
    bl_idname = "Name"
    bl_space_type = 'VIEW_3D'
    bl_region_type = 'TOOLS'
    bl_category = "Tools"

    def draw(self, context):
        layout = self.layout
        layout.row().operator("macro.start")


class Macro(bpy.types.Macro):
    bl_idname = "macro.start"
    bl_label = "Start Sequence"

class SomeOperator(bpy.types.Operator):
    bl_idname = "macro.finish"
    bl_label = "Finishing Operator"

    def execute(self, context):
        # do something else after transform
        return {'FINISHED'}


def register():
    bpy.utils.register_module(__name__)
    Macro.define("TRANSFORM_OT_translate") # How can I give arguments to an existing Operator?
    Macro.define("MACRO_OT_finish")

def unregister():
    bpy.utils.unregister_module(__name__)

if __name__ == "__main__":
    register()

Macro.define("TRANSFORM_OT_translate") returns a OperatorMacro which has a properties attribute.

Eg:

op_macro = Macro.define("TRANSFORM_OT_translate")
op_macro.properties.value = (1, 2, 3)
