Is there any alternate way to get Approval Role in iStore

Hi All,

In test instance I've system administrator responsibility. but as soon as i register in iStore(B2B Scenario) it redirect me to Account Approval. But when i go CRM HTML Administration >User Maintenance it gives me an error " insufficient Approval privileges" I know it requires " JTF_SYSTEM_ADMIN_ROLE" Roles. Then i need to contact DBA and They login through SYSADMIN Account in Instance and assign this roles to me. Evey time when instance get cloned same error i get. i can not maintain and Approve user. is there any alternate way to get this role and assign to me.
