Setting Silent Alert for Panic Button on Keypad and Keyfob

I'm newer to the SimpliSafe system, and it appears as though the non-standalone panic buttons that are on the Keypad and Key Fob, do not have an option for "Silent" mode. It appears as though Silent is only available for the standalone button.

Am I missing something, or is this correct?

I know I could also use the duress pin code on the keypad, but in the case of an attack upon entry, it is harder to remember an alternate number that is never used, rather than to press a "slightly hidden" button. The last thing you want in a forced entry situation is to make an obvious move to a standalone button or to have the alarm go off. That's how you get unalive. Hopefully I'm missing something here. I can see how you may not want that on the keyfob due to the ability to accidentally set it off, but on the keypad it's much more difficult to accidentally trigger.
