No rows returned in subquery

I have the following query in a PL/SQL block:

select nvl(include_in_dif, 1)
   into m_include_in_dif
  from pcc
 where pcc in (select nvl(pcc, 'NONE')
                 from gdls_z_expanded_boms
                where bomtype = 'MRP'
                  and partnum = 'DIFREPORT-001');

The Sub query returns no rows so the whole query returns nothing. I would like m_include_in_dif to default to '1' if no rows are returned. The above query does not do this of course.

Can I do this in one query. Any ideas ... ?

select nvl(include_in_dif, 1)
   into m_include_in_dif
  from pcc
 where pcc in (select max(nvl(pcc, 'NONE'))
                 from gdls_z_expanded_boms
                where bomtype = 'MRP'
                  and partnum = 'DIFREPORT-001')
;
