PL/SQL :: Rename Only Two Names In Column Report_headings1?

I need to rename only two names in column report_headings1. But in order for me to see all other names I need to use all of them in decode function. Is there an easier way to write this Select Statement.

select days_start, days_to,
decode(report_heading1,'31 Or More days', 'Future', '00 Dispute/Pend', 'Dispute or Pend', '1 to 30 Days', '1 to 30 Days',
'31 to 60 Days', '31 to 60 Days','61 to 90 Days', '61 to 90 Days', '91 Or More Days', '91 Or More Days' ) report_heading1, report_heading2, type
from ar_aging_bucket_lines lines, ar_aging_buckets buckets
where lines.aging_bucket_id = buckets.aging_bucket_id;
