Headers On A Report

I wanted to show header titles for each group of accounts. Ho would I be able to do that. The query that I have right now is:

select * from apcopah
where substring(ap_control_acct, 1, 4) = '1624'
and date_vendor_inv >= '2001-08-01'
or substring(ap_control_acct, 1, 4) = '1631'
and date_vendor_inv >= '2001-08-01'
or substring(ap_control_acct, 1, 4) = '1632'
and date_vendor_inv >= '2001-08-01'

I would like it to look like this:

Utilities

Ap_control_acct date_vendor_inv
1624 2001-10-01
1624 2001-12-01

Audit Fees

Ap_control_acct date_vendor_inv
1631 2002-09-01
1631 2002-10-01


Is this possible?
