Call WebService in a loop

Hi,

I'm a new user to soapUI and I would like to do a loop in my Web Service call.

I have a WebService called CreateObject which create an Object with some properties (and store it in DB after), and I need to call this WS 1000 times using a loop. So I have some questions about that:

1) How to do a loop
2) Some properties of the object need to be unique, is it possible to set a new value for each step of the loop?


Thanks in advance for your help!
