Is there a way to edit stored period performance in Primavera Cloud(like you can in P6)?

We are new to OPC and noticed that past stored period performance cannot be edited. This is frequent need for us, when corrections are made or if previous estimates get converted to actuals and so on. This should be an obvious thing to be able to do LIKE WE CAN in P6. Are we missing something? What is the workaround? Thanks.
