You would need to group the units by inserting another .slice unit in
the hierarchy (by setting Slice=). Once you have that, you can easily
define limits for that new .slice unit.

Depending on what you want, a more straight forward approach could be
to turn it around and give certain user slices and system.slice memory
guarantees using MemoryMin=/MemoryLow=.
