Droid # is the apt. buzzer. Can I set it to automatically answer?

[Wall-E-spence]

As above, my droid is very handy at me calling my apt. and answering on my phone (pressing 9) and buzzing myself in if I've forgotten my keys. Is there a way to program the phone to answer that number and automatically press 9? Thanks for your time even if you don't respond -you guys rock! -Spencer
