Make label reference contain section number

I have some code that looks like

section*{Problem 1}

begin{enumerate}
   item Hello
   item label{problem-2b} Yes
   item cref{problem-2b} Welp
end{enumerate}

I want the reference to appear as

problem 1a) 

as a refference. How can I include the name of the previous section into the reference? I already have the exercise number as a counter.

For a “MWE” of my actual problem see below
