DHCP - Multiple scope splited by SITE

Hello, good afternoon!

I have a mission to replace the old AD structure (SBS 2011) with a new one and now with multiple sites in different countries.

We have:

AD Sites and Services

Site A - Subnet: 192.168.44.0/24
Site B - Subnet: 192.168.48.0/24
Site C - Subnet: 192.168.61.0/24

DHCP

Scope 192.168.44.0
Scope 192.168.48.0
Scope 192.168.61.0

My question is: How can I associate a "DHCP scope" to a "SITE"?
My need: Distribute just one specific IP range (Scope) by SITE.

Thank you!
