Need for manually adding unmanaged network

[#1]

Hi Community experts,

I have a need to add add unmanaged, or reserved, networks but can't seem to find how. 

Regardless if it's for reserving future needs, or as in my case need to more clearly visualize reservation of networks managed by a separate Grid, I have yet not found a way of adding such networks in Infoblox.  

I can add unmanaged network using AD Sync, but this won't allow me using the needed information of the blocks so this would only raise more questions internally.
