How to influence load balancing based on the source IP address

Hello,

I have 2 GTMs in 2 Data Centers that geographically dispersed, I want users to be directed to servers that are local to each Data Center instead of the GTM returning an IP address of a server that is located in the opposite data center when performing a DNS query, can I set this in the GTM to prefer a pool based on the source IP subnet? Thanks in advance.
