notching tubes in solidworks

Wondering how you guys are notching tubes in SolidWorks when you want to show the tubes trimmed-back to full wall thickness. When working with flat sheetmetal parts, usually just cut through the part where it will mate with another part, and then convert any edges that need to be trimmed back from one side of the part to the other and use those to create new cut lines. Never really worried about it with tubes because I was always working with holesaw-type notchers, so didn't need to model the trimmed tubes. But what's the best way to do that? Don't see any options in the Weldment feature dialogue box, and creating a profile to sweep around the lines at the end of each tube manually seems really tedious. Any suggestions? Asked this question on a motorsports forum (http://www.race-dezert.com/forum/showthread.php/102129-notching-tubes-in-solidworks) and the replies so far are not encouraging. Hoping there is a better way to do this, as it seems like an essential part of fabricating almost any type of tubular assembly. Assumed that it was just something I hadn't figured out how to do yet, but is this feature really missing from Weldments?
