How to construct a DSGE model with two steady states before and after a structural break

Dear Johannes,
Thank you very much for your helpful guidance, I am grateful.
I have a question, we plan to construct a DSGE model given a structural break in 2020 Q1, the steady state prior to 2020 Q1 is different from the steady state on/after 2020 Q1, is there any type of model to capture this shift in steady state values due to a structural break?
Thank you very much and look forward to hearing from you.
Best regards,

Without more context on what exactly you are trying to model, it’s hard to tell.
