Low power project, interrupt attached to 6 buttons

hi -


i have idea i'd verify! use 6 buttons on arduino, power thing using 3.3 volt coin cell , sleep until 1 of 6 buttons pressed.

the buttons switching ground , each have single lead going input pin. i've enabled pullup resistors pins read high when button switches open , low when pressed.

i know can wake arduino using interrupt. mine has 2 need 6.
can wire 6 buttons single interrupt pin using diodes? work?


thanks

anyone?
