Hello Hrishikesh,
Multiprovider will ultimately pick the data from the underlying Objects be it DSO, InfoCibe , InfoObject, Aggregate . So in orderto acheive the desired output you need to maintain the same property on the underlying Objects.
In that case, as Raman suggested ,maintain the same properties in InfoCube level and then try to explore the same.
Hope this helps !
