Thanks for getting back to me,
I took some snapshots of Serum and TAL-Mod that display the features I'm talking about. I no longer have DUNE 3 but it also had Random, Constant/Fixed, and Alternate Mod sources. I'm not great at explaining things so I'm sorry for that. Hopefully this clarifies what I mean.
I find these features really useful in my workflow and think it would be a great addition to ANA 2.
