Multiple awards needed for this ITN?

I'm a OW/AA guy and not all that familiar with Star Alliance and would appreciate any help.

I have 186,000 UA miles (160,000 AS if that helps) and would like to route (in business):

SEA-XXX-NBO stop NBO-XXX-MNL (a stopover in ADD would be good) stop MNL-XXX-Southern Europe.

Will this require 3 awards? NA-SAfrica (60k); SAfrica-Asia (60k); Asia-Europe (62.5k)

Thanks
