I need to link marian reforms with ancillaries, but how?

[Atraphoenix]

I am working on my submod, I got stuck with the handling Marian Reforms with ancillaries.
So as to code imperial legions that I aim to triggle with marian reforms, what must I do, I am searching all ancillary triggers at the moment but they are high in number, so if a dev team or any trait and ancillary guy can help me; I will be appriciated,

My Planned Republican legions:

Legio I Germanica
Legio II Augusta
Legio III Gallica
Legio III Augustica
Legio V Alaudae
Legio VI Ferrata
Legio VII Claudia Pia Fidelis
Legio VIII Augusta
Legio IX Hispana
Legio X Gemina Pia
Legio XI Claudia Pia Fidelis
Legio XIII Gemina
Legio XXII Deiotariana

I am planning add when the campaign starts.

and the imperial legions that I am planning to add with marian reforms:

Legio I Italica
Legio I Minervia Pia Fidelis
Legio I Adiutrix
Legio II Adiutrix Pia Fidelis
Legio II Traiana Fortis
Legio III Cyrenaica
Legio III Italica
Legio IV Flavia Felix
Legio IV Scythica
Legio V Macedonica
Legio VI Victrix Pia Fidelis
Legio VII Gemina
Legio X Fretensis
Legio XII Fulminata
Legio XIV Gemina Martia Victrix
Legio XV Primigenia
Legio XV Apollinaris
Legio XVI Flavia Firma
Legio XX Valeria Victrix
Legio XXI Rapax (Predator)
Legio XXII Primigenia
Legio XXX Ulpia Victrix

Important : I am adding legions under their Legatus offices not the units. Just Legates in fact.

As you see there I do not want to levy Imperial Legions during the campaign start.

Thanks beforehand

So you only want these ancillaries to start showing up after the Marian reforms?

If so, add the following condition to your trigger:

          and Trait MarianControl = 1

This trait signifies that the Marian reforms have taken effect for this general.
