Can systemd-run create temporary cgroups for temporary commands with resource limits?

I'd like to limit the resource consumption of temporary commands with cgroup created by systemd-run, similar to what cgcreate does instead, but I'm not sure if that makes sense? I'd like to make sure I'm trying this correctly, thank you all!
