Multiple Response with Mock Service

Just wondering if its possible for a mock service to be set up so that it can return multiple responses.

normally we go

return "My Response"

but i want to go

Return "My Response", "My other Response" etc..

can this be achieved when using a groovy script?

Thinking about this more, i dont want to have 2 responses. i want my mock service to be able to spawn off a new Request i guess?  perhaps this is something you cant script.. calling a Request via script/


eg

Return " My Response"

Exec "My Other Request"
