Z Field in the Storge Bin

Hello,

I want to create a Z Field in the Storage Bin(/n/scwm/ls01)where it can carry 30 char lenght.The purpose of this Z field is i want to store my Legacy bin numbers as Reerence.I should be able to load the reference bin as well when i do the Bin Upload with the SAP Provided Template.

This Reference Zfiled should also be seen in the warehouse Monitor.

Please Advice on this.

Thanks
