How to create multiple connection

Currently it's supported for single host. How can we use it multiple host? Something like below in application.yml file
sms:
 smpp:
  one:
   host: xxx.xxx.xxx.xxx
   user-id: uname1
   password: pass1
   requestDelivery: true
  two:
   host: yyy.yyy.yyy.yyy
   user-id: uname2
   password: pass2
   requestDelivery: true
 async:
  initial-delay: 30000
