ESC Temperature on OSD

I have my ESCs configured with DShot and I have the BLHeli telemetry enabled and working. IDE like to display it on the OSD but the OSD only displays the temp from ESC1. My telemetry shows the ESCs a 3-6. I assume this is because that is the outputs they are connected to. Is there a way to change the high esc temp show in the OSD or could it show the highest temp?

Is this something that could be custom coded?
