reporting services - How do you add not equal to function to the default values of a report parameter? -

i have list of value , want default 1 of them. don't want have add 10 unique value functions, <> "value" possible?

is multi-value parameter based on query? if so, select default values parameter query excludes value want ignore.

for example, if parameter values gotten query:

select code, description codetable 

then use following query default values:

select code, description codetable code <> "notthiscode"
