You can use the /voicecom command to call any voicecom and accompany it with any text on-the-fly. Or, as Andrez mentioned, you can edit menu_voicecom.cfg to change the menu. You can also add specific keybinds that have your own text accompanying a voicecom sound.
I believe R4zor made a custom menu that simplified custom voicecom text on-the-fly.
