Can Synonyms Be Used To Replace Hundreds Of Lines?

Hello

I'm looking for a way to store a large chunck of text (200 lines) in a variable which can be called in different objects within the database.

For example: I have several stored procedures that create the same temp table which exists of 200 column names over and over again.

It would have to look like this

Import myScript (I keep thinking of Import like used in .NET)

and myScript could exist of:

CREATE #MyTable(
...)

or even some simple text or a part of a sql statement.

I'm familiar with synonyms but you can't use that in this scenario.
Then I thought of functions. The scalar function returns a result, not what I want here. Table valued function return tables, not what I want.

Many thanks in advance!
