I would like to be able to specify different script blocks inside a snippet that would work differently based upon the sql server version of the server I am connected to.

Or.... optionally have a version indicator on the snippet to perform the same thing. Then if two snippets share the same name it would apply the correct one based upon version.

EX:

:if $version_major$ >= 13
    CREATE OR ALTER PROCEDURE [$dbo$].[$proc_name$] (@param1 INT) AS BEGIN
        $CURSOR$SELECT @param1
    END
    GO
:else 
    IF OBJECT_ID('[$dbo$].[$proc_name$]', 'P') IS NULL BEGIN
        EXEC('CREATE PROCEDURE [$dbo$].[$proc_name$] AS BEGIN SELECT 1; END;')
    END 

    GO
    ALTER PROCEDURE [$dbo$].[$proc_name$] (@param1 INT) AS BEGIN
        $CURSOR$SELECT @param1
    END
    GO
:endif
