Apple Logic Pro /LogicExpress Discussion

Here's something that's bugging me and I know the answer must be simple... 
just can't work it out 

I am happily using Ultrabeat to build my drum sounds, but obviously I need 
several different patterns to complete the song. So I go into Ultrabeat and 
build my main pattern, drag it into Logic arrange area, and the region calls 
itself Ultrabeat. Can I save that pattern in Ultrabeat before editing it to 
give me another pattern? What seems to happen is that I change the pattern 
and then it also changes in the Arrange area. 

Thanks in advance for any help. 

By the way, thanks to the advice given previously I bought the new 24" iMac 
rather than a Mac Pro, as a compromise between the laptop I was using and a 
big piece of kit that I wouldn't feel particularly comfortable with as a 
technophobe. Too early to say how I am getting on with it, but the screen is 
fantastic. The only thing is, my eyes hurt after using it!
