BPC Multiple Transformations triggering in one Data manager package

Hi Experts,

I need to send data from BI to BPC (BI info cube) i have created two transformations one for Revenues(sign data) and one for Volumes(signdata), since we have only one sign data in BPC and i am getting two keyfigures from BI so i created two transformations.

As of now i am running two transofmrtaions separately, now i need to combine these two and run through one Data manager package, can any one tell me the procedure to run two transformations through one DMP.

Thanks In advance
