A shorter way of specifying a set in MDX - mdx

Question

Is there a briefer way of specifying a set in MDX?
I know I can do something like :
{[Debtor].[TRADING DEBTOR CODE].&[AU-000013],[Debtor].[TRADING DEBTOR CODE].&[AU-000020]}
but once you get over a few members, it becomes incredibly verbose.
I'm looking for something like
MagicFunctionToMakeASet([Debtor].[TRADING DEBTOR CODE],'AU-000013,AU-000015,AU-000013,AU-000015,...')

Answer 1

Are they in sequence at all? If so, could you do
{
[Debtor].[TRADING DEBTOR CODE].&[AU-000013] :
[Debtor].[TRADING DEBTOR CODE].&[AU-000020]
}
To give you a set of codes 13 though to 20 inclusive?
Failing that, take a look at InStr and see if it can help, it looks like it might - Or you could create some subsets using it and then combine into your final set?

From the above MSDN:
WITH SET [ChardonnayChablis] AS
'Filter([Product].Members, (InStr(1, [Product].CurrentMember.Name, "chardonnay") <> 0) OR (InStr(1, [Product].CurrentMember.Name, "chablis") <> 0))'
SELECT
[ChardonnayChablis] ON COLUMNS,
{Measures.[Unit Sales]} ON ROWS
FROM Sales

Answer 2

There are various shortcuts. If you just want all the 'children' of a certain member, use Descendants() or .children. Or get all the members at one level with .members. You can specify a range between two members, or use a filter to match some sort of critera.
What were you after? I'll try to give a more specific example...
