Omni trials are fully-functioning versions of the software, no concern there.
As for the multiple lists, is this an example of what you want?
I opened the Utilities drawer, clicked on "All Level 2 rows", brought up the Row Inspector, Numbering tab, and set the numbering to Roman. You can even have different lists numbered in a different fashion if you override the styling by selecting the elements of the list you want to change, then doing the same process in the inspector.
