Changing Resume Insulin Alarm

So, does anyone know if it is possible, and if so how, to extend the Resume Insulin alarm? Fifteen minutes is awesome if you just had to disconect for a few minutes and forgot to push the button after reconecting. However, my showers last a good 30 minutes, and a high-pitched alarm going off every three minutes at 5:30 in the morning isn't the greatest start to the day.
Thanks!

When I disconnect for the gym and shower I just let it continue delivering basal. You will only lose a unit or 2. This amounts to a drop or 2 coming out of the tube. No big deal!

Can you do a 0% temp rate for the duration of your shower?

I just disconnect and let it be as well, then run a 200% temp basal to cover the time it took.
Never thought of a 0% temp basal while disconnected- will be doing that in future as it will help keep my basal dose records more accurate. I'm very insulin sensitive so I like to keep a good eye on TTD.

Yes a 0% temp basal can be done and is a good solution. I prefer to do the "stop insulin" thing for showers, just so I have a reminder to hook back up, cus it doesn't always occur to me.

I do however use the 0% temp basal for an exercise class for 1.5 hours as all THAT beeping would surely get on everyone's nerves so "stop insulin" would not be appropriate for that.
