YTD and QTD hierarchy under Period Dim in Planning

I’ve created Hyperion Planning application. Hyperion planning automatically create Period dimension with Year Total hierarchy. Year Total has Q1, Q2, Q3, and Q4. I also enable DTS for period dimension. How do I add YTD and QTD hierarchy under Period dimension? I can only add child. I cannot add sibling in Period dimension.

I would like something like this
Period (Never Share)
Year Total (dynamic Calc) Note: Year Total Hierarchy was created by planning
