Loading data into two cubes

We want to set up a delta refresh from R/3 data that will pull data into two cubes. One cube I want all the records to be loaded, in the second cube I want to filter the records that are loaded into that cube. I can figure out how to load the data into two cubes, but can I place a filter on one of the loads. (i.e. only load records of where type = 'X')

Thanks,

Chris
