Forming Tool - Creating a hole within the form

This has been driving me nuts. I can't seem to figure out how to create a through hole in my forming tools. I always have to cut-extrude after I form the dimple. Someone then sent me a forming tool and it contained a split-line feature that created a complete through hole, but I can't seem to duplicate it on any new forming tools I create.

Any help would be greatly appreciated.
