riswhois: reporting parent routes

Could riswhois generate statistics of "parent routes" for given route?
[ parent, not ancestor]

My goal is achieve better coverage of IP->AS mappings based on riswhois 
provided data. Unanimous AS reports (after ignoring default route) give very 
good starting point I would like to extend.

For 65.54.160.0/19 I would like to know how many of 58 rispeers reporting 
the route reports also 65.52.0.0/14 route as belonging to AS8070.

e.g.
route:        65.54.160.0/19
origin:       AS12076
[...]
num-rispeers: 58
numrp-parent: 58 65.54.160.0/19 AS8070

P.S. As security precaution riwhois may limit number of parent routes 
reported to e.g. <10
