Design studio over UNX Key and text

Hi All

I'm working on a model over a UNX with D.S 1.2 SP1 patch1

I have a strange question

Some of the components like Dimension filter, list view and others work with Key and text like BW does

I want to display text and filter by the key, but in UNX they are in 2 fields and not one like in BW.

It doesn't make sense that SAP didn't think about it

Any ideas???
