Chime in Home Mode for disabled sensors

I just spent a good amount of time on tech support attempting to verify/understand this lack of capability as well.    I want to arm in HOME mode - e.g. to protect my street side doors and windows while in the house -- but need the chime active (along with SMS or notification alerts in case I'm out of earshot of the base station) in case a grandchild goes out a rear patio door toward the pool.   Also helps me know someone is through a door or window that's not currently alarmed while I'm at HOME in HOME mode.       Works perfectly if I leave the alarm OFF, but goes silent if I put the alarm in HOME.   Huh?    What logic is that?   They recommended alarming everything which is a silly option when there are people in and out of the rear patio.      Ugh.
