Entry / Exit Delay, allow for custom time and/or add 15 seconds

My feature request is to add 15 seconds to the list of entry/exit delays, or just the ability to make it a custom amount of time. Currently the entry / exit delays are 30, 45, 60, 120, and 180 seconds. I would like a very short delay for when I am home. I use home mode when sleeping. 30 seconds is a very long period of time if someone were to break in while sleeping for the alarms to start sounding. At the same time, sometimes I or another member in the house forgets to disarm home mode in the morning, inadvertently setting of the alarm. It would be great to have a 10 or 15 second option, or just give people the ability to set their own delay times!
