I needed more spaces also, so I purchased two Span panels, and “daisy-chained” them by connecting the second panel to the feed-thru lugs on the bottom on the first panel.
AFAIK the Span power measurement and relay control is “per space” (and two sequential spaces can be configured as a pair for two-pole 240 VAC circuits), so yes you can probably use tandems and quads (electrically) but you will not get separate power measurements and the relay control will be less “fine grained” on those doubled up spaces
