Combined rotation (2Ga-540 Ma + 550-0 Ma)

Hi all, I am wondering if there is a way to “combine” two rotation models: one from the GPlates 2.3 default model (Muller2019-Young2019-Cao2020_CombinedRotations.rot ) and the one from Li et al. Earth-Science Reviews ( The formal one covers from 0-550 Ma and the latter one covers from 540-2Ga…I know it may be a difficult thing…

Does anyone know if there is an existing, coherent rotation model that goes from ~1-2Ga to 0 Ma?
