In Odoo 8 you can patch the method report_download of addons/report/controllers/main.py like below (between FIX START and END). It will then use the code for the attachment attribute in the report action definition. As the system will then always also save the file as an attachment in the database you can change the behaviour further to only save in the database when attachment_use is set to True. In this way no extra fields need to be added and views changed.

You can set the attachment attribute of a report action for example in this way:
<?xml version="1.0" encoding="UTF-8"?>
<openerp>
<data>
<!-- rename the file names of the standard rfq report -->
<record id="purchase.report_purchase_quotation" model="ir.actions.report.xml">
<field name="attachment">'RFQ_'+object.name+'.pdf'</field>
</record>
</data>
</openerp>
This is the patch of _check_attachment of the Report object in addons/report/report.py to modify the attachment_use behaviour:
@api.v7
def _check_attachment_use(self, cr, uid, ids, report):
""" Check attachment_use field. If set to true and an existing pdf is already saved, load
this one now. Else, mark save it.
"""
save_in_attachment = {}
save_in_attachment['model'] = report.model
save_in_attachment['loaded_documents'] = {}
if report.attachment:
for record_id in ids:
obj = self.pool[report.model].browse(cr, uid, record_id)
filename = eval(report.attachment, {'object': obj, 'time': time})
# If the user has checked 'Reload from Attachment'
if report.attachment_use:
alreadyindb = [('datas_fname', '=', filename),
('res_model', '=', report.model),
('res_id', '=', record_id)]
attach_ids = self.pool['ir.attachment'].search(cr, uid, alreadyindb)
if attach_ids:
# Add the loaded pdf in the loaded_documents list
pdf = self.pool['ir.attachment'].browse(cr, uid, attach_ids[0]).datas
pdf = base64.decodestring(pdf)
save_in_attachment['loaded_documents'][record_id] = pdf
_logger.info('The PDF document %s was loaded from the database' % filename)
continue # Do not save this document as we already ignore it
# FIX START (commenting out below lines and indenting the else clause one level down)
# If the user has checked 'Save as Attachment Prefix'
#~ if filename is False:
#~ # May be false if, for instance, the 'attachment' field contains a condition
#~ # preventing to save the file.
#~ continue
else:
save_in_attachment[record_id] = filename # Mark current document to be saved
# FIX END
return save_in_attachment
