How use many external IP in Pritunl?

Hello!
There is a VPS, three public external IP addresses are configured on it. How to assign different external IPs to each of the servers in organization?
For example
Public1 IPv4 assign to Server1
Public2 IPv4 assign to Server2
Public2 IPv4 assign to Server3 ?

Pritunl v1.32.3552.76

i believe you can click settings in the top right and specify public ipv4 address
