Change Forticlient profile IP automatically

Hi

We are in the process of switching ISP which will obviously present us with a new public facing IP address.

Currently all our Work From Home staff have Forticlient set up with the current IP address, but these will require changing in a few weeks.

Is there a way to automatically update this IP address across our fleet, or am I looking at doing it manually, or with powershell etc?

TIA

John
