Are specific "route" objects in RIR databases needed?

Hi,

for example there is a small company with /22 IPv4 allocation from
RIPE in European region. This company is dual-homed and would like to
announce 4x /24 prefixes to both ISPs. Both ISP's update their
prefix-lists automatically based on records in RIPE database. For
example Level3 uses this practice at least in Europe. If this small
company creates a "route" object for it's /22 allocation, then is it
enough? Theoretically this would cover all four /24 networks. Or in
which situation it is useful/needed to have "route" object for each
/24 prefix?

regards,
Martin
