Time dependent hierarchy update in BPC 10.0

Hi BPC Experts,

I have been maintaining master data for cost centre manually in BPC 10.0. so master data is not coming from BW.

But as per business requirements, I might need to do "cost centre category changes " means moving one costcentre from one Cost centre group to another group. Can you suggest me how i can do this time dependent hierarchy maintenance in BPC 10.0 manually.

Regards,

Vishu
