Can T slim be changed from mmol to mg/dL?

I was fortunate to receive a loaner tslim pump in the event of mine breaking while I wait for replacement. It’s in mmol and I’m really terrible at remembering anything numerical and only familiar with mg/dl. Is it possible to switch the unit of measurement? I’ve looked all over settings and can’t seem to find anything. Are t slims just EU or US and they can’t be switched?

Also, is it possible to get the sensor readings on my “new” loaner pump with my sensor session already started?
