New Named Set in SSAS used in Pivot Table - MDX - ssas

Question

I created a New Named Set called DB III o. PE defined as DB III, Umlage HL, Umlage NV, Umlage UL .
When I use this new Set in a Pivot Tabel or in MDX I see the content of this Set and not his given name DB III o. PE.
Is there a possibility to see the given name instead of his content?
Example attached:
The set is created like this:
UPDATE:
I created also a measure called [Amount Standard Set] because before Set I needed first to multiply with -1 the Amount of Umlage HL, Umlage NV, Umlage UL .
The measure is defined as:
case
when [Kostenart Hierarchy].[Kostenart Hierarchy].currentmember= [Kostenart Hierarchy].[Kostenart Hierarchy].&[148]
then -1* [Measures].Amount
when [Kostenart Hierarchy].[Kostenart Hierarchy].currentmember= [Kostenart Hierarchy].[Kostenart Hierarchy].&[147]
then -1* [Measures].Amount
when [Kostenart Hierarchy].[Kostenart Hierarchy].currentmember= [Kostenart Hierarchy].[Kostenart Hierarchy].&[150]
then -1* [Measures].Amount
else Amount
end

I think it is behaving as it should. A set is several distinct members.
You require a custom member that is the amalgamation of your set.
Create a custom member called DB III o. PE Agg and define it as something like the following mdx:
`Aggregate([DB III o. PE])`
This is using the Aggregate function:

Create this custom member in the dimension where the elements of the set {DB III, Umlage HL, Umlage NV, Umlage UL} are found.
If you are using Excel 2013 you should have a option in the OLAP Tools menu "MDX Calculated Member.."
