Flat file Import with multiple years of budget data

Hello,

We are planning to use flat file to upload budget values into BPC cube using standard Import package and user wants to budget for more than one years.

User propsed a file format which is handy for them while entering budget values. In his format all 12 months are in columns and year as row. I know we can use MVAL funtion to handle multiple key figures to upload but is there any function or workaround in transformation file to handle to upload this kind of file without using BADI or excel macros.

Thanks,
