Systematics on upper limits with RooStats

Dear experts,

I am attempting to use RooStats to get the CL if my signal mode is observed or to set an upper limit on a parameter, R, if case of no observation. I have built a fit model using RooFit, and the fit is parametrised in terms of R.

I’ve managed to calculate the upper limit using the Asymptotic Calculator. In principle, the calculators are agnostic of systematic uncertainties but I was wondering if there is any option to include systematics on upper limits. So my question is, how could I calculate systematics on the upper limit?

I would appreciate any advice regarding upper limit calculation using RooStats. I have looked through a lot of tutorials and slides to find any answers, but I am still confused.

Thank you,
