Can you elaborate?
If you're looking to send a random phrase from a list, you can use the "{TXTRANDOM:}" token:
Quick Input, '{TXTRANDOM:Hello;Hi;Howdy}'
You can also embed this token inside another to provide more variation:
{TXTRANDOM:Howdy-ho {TXTRANDOM:partner;buddy};{TXTRANDOM:Hello;Hi;Howdy} {TXTRANDOM:there;}}
