How to add hosts into groups based on the name in zabbix during auto-registration?

Question

Zabbix

Actually, the question is this: can zabbix arrange hosts into groups based on regexp during auto-registration (not detection, but registration name)?
Those. let's say hostnames starting with 01 is the center. region, 02 Far East, I create an auto-registration action, in it the condition "Host name contains ^01", in the operation "Add to host groups: 01 Moscow". However, all nodes passing auto-registration are poured into the discovered hosts group. Where am I wrong?
