No need for something like new default section. You can just use :

===code begin===
{$MACRO ON}
{$DEFINE TMyRecord_Default := (i: 1; s: 'foo')}

type
  TMyRecord = record
    i: integer;
    s: string;
  end;

var
  myRec: TMyRecord = TMyRecord_Default;
===code end===

you can also try new management operator "Initialize":
