Hi,

Max showed the correct way. There is another way to do this, based on your
previous steps:

After having added the \unroll, you input \item, then you get an item. After
having finished this item, you press enter then you get another item (with
unrolling features). Here you get the same effect as Unroll -> Itemize.

Best,
Frank
