I'd like to adjust the radius used for the bends on my sheet metal part.  However, I don't want to make a global change to ALL the bends.  In other words bends 1-3 would have a radius X, bends 4-5 would have radius Y and then bend 6 would have radius X.  Make sense?  How do I do this?

It's important to point out the way the part was created to begin with...

Looking through the help tutorials it looks like I'm not creating the parts correctly (or conventionally) to begin with.  But...I was just following the process used by the person before me.  Hmm...

I draw the profile of the part using a line.  Then I go to Sheet Metal -> Base Flange

select the gauge metal and the length of the part

It's worked fine so far...but now I'm running into a new issue.  I need to use multiple bend radius on the same part.

Any ideas?
