How can I generate metahuman identity with modified dna(by metahuman calibration) for metahuman performace?

I want to use video to drive my modified DNA, but it seems that only the metahuman identity generated in UE can be used in the metahuman performace. Is there any way to re-import the DNA file I modified using metahuman calibration into UE to generate a metahuman identity?

Did you ever get an answer, or figure this out? I’d like to do the same thing.
