Imprecise Probability Modelling using the Two Level Metamodeling approach


First and foremost, thanks for your enjoyable UQLab.
I read a marvelous thesis from RSUQ, Surrogate models for uncertainty quantification in the context of imprecise probability modelling.
I was wondering how to apply the Two-level Metamodelling methodology in the context of “Imprecise Probability Modelling” in UQLab.
Does it seem the UQLab users can take the advantages of the p-box approach? How?
Is there any example to download and learn?

I really appreciate your time and consideration
