I am planning to build a WordPress MultiSite and just

Hello,

I am planning to build a WordPress MultiSite and just needed some clarity.

I am doing a local bloggers network and will be Domain Mapping Every site on the network to their own Unique URL.

The Question I have is, Will the blogs on the network be able to create their own subdomains? I ask because some of the niche blogs will need to have their regular domain and a subdomain too.

If this is possible how does it get implemented?

Thanks.
