Is it possible to manage key date "TDH" on reports?

Hi gurus,

What is time dependent hierarchy (TDH)– Hierarchies represent parent child relationship for a dimension that helps in aggregation/rollup of data. So the department figures roll up into company, products roll up into groups /categories etc. Time dependent hierarchy allows defining the hierarchies based on a time range and the roll up behavior will be different based on the time the data belongs to.

More information:

It's about Time... Dependency in SAP BPC 10

I need manage the context "Key data" on my Excel´s reports, like a dimension with EPMContextmember( )

Why?  Because I have Time dimension with YEAR.T1, YEAR.T2, YEAR.T3, and YEAR.T4 values and Timedimensionmust match "Key data".

For example:

If I select 2015.T1 my key date is 01/01/2015 to 31/03/2015,

                 2015.T2 my key date is 01/04/2015 to 31/07/2015,   and so on.

It has no sense to input data in 2015.T2 (dimension time) with TDH in 31/09/2015 (key data) for my project.

Any suggestions?

Thanks
