As I understand, the AFRINIC IRR won’t let you register a /21 route object unless you have a /21 intnum object (or a less-specific).  You don't have that; you have a bunch of /24 inetnum objects.

It seems to me that there are two plausible ways to handle this: (1) combine your multiple /24 inetnum objects into a  single /21 inetnum object; or (2) let AFRINIC write some code to allow the less-specific route to be authenticated by multiple /24 inetnum objects.

I am not very keen on option 2.  What are the barriers to option 1 (combining your multiple /24 inetnums into a single /21 inetnum)?
