Unfillet curve / turn blend&fillet into sharp corner?

Is there any tricks to quickly unfillet a curve?
I always have to extend them and trim. It became tasking with a lof of corners if my fillet didn’t turned out the way I like. I wonder if there is a much faster way to do this on a curve? (same logic as create hole - remove hole) Or if any trick to delet certain control point to achieve the same effect? Thanks
