Yes.
It enables PLA/PVA combo or PLA/PETG for supports, it also maximizes comfort and saves time by taking care of loading filament into printer.
Plus it doubles as solid drybox.
So, yeah - think of it like having paper printer that you have to pour ink before any print - AMS is your buffer- like cartride. Pour ink once and consumer until done.
Oh, and recently I have been printing batches of these modesty paneling for SimRigs - Print plates of 600-1.2kg of material. So, I load 4 same spools and it just continues from other spool when running out.
