Custom number range for equipments in S/4HANA Public Cloud

Hi,

ist it possible in S/4HANA Public Cloud to define custom number range for equipments? I Just see the possibility to change the range but not to define a custom intervall and assign it to an equipment type. My goal is to sync serialnumber and equipment number. For this equipments must have the same interval. Seems there is no button to create a new one.

Regards

Gabriel
