How ISP's in ARIN region create automatic prefix-filters?

Hi,

as I understand, ARIN whois database does not contain "route" objects,
which are used for example in RIPE region for automatic BGP prefix
filter generation. How does this work in ARIN region? I know that at
least some ISP's operating in ARIN region use their own whois
databases(for example rr.level3.net) which mirror content from other
RIR databases, but are there other methods how they update their
internal databases with records?

regards,
Martin
