You should create a route object for each route that you announce, if
you announce 4 x /24 you should create a route: object for each /24. 

Some providers will create filters solely based on existing route
objects, others will create filters based on all route objects, AND 
allow up to a /24 regardless. I would err to the safe side. 

Kind regards,

ps. Can you please send 20 dollarcent per /24 to my paypal account
(job at instituut.net) with the reference "deaggregation fee"?
