CIDR lookup with normal lookup- Can I add single IP's to the same lookup file/definition?

Hello,

I have created a lookup definition for CIDR. The CIDR matching works just fine and I am able to whitelist the IPs in that particular subnet range.

However, I wanted to know if I can add single IP's to the same lookup file/definition(CIDR lookup) as well?

I want single IP matching in the same lookup table where I have added the IP subnet.

How to proceed about this?

Add single IPs to the lookup as 

n.n.n.n/32

i.e. a CIDR range of 1
