Subd continuity

I have a subd model I’m working on and I can seem to control the continuity very well. I’m wondering if there is a way to force 2 lines to connect together to form a single continuous line. It seems it just randomly picks a line to follow, I’ve tried forcing it with points but it ends up just doing it further down the line.

Here is what I’ve been working on. I’ve found a workaround but it’s tedious. as you can see the continuity is a bit of an issue, I had to separate a section to make it possible to do what I wanted.

I have found that you can kind of control it by adding a 3-point termination and then removing the original center line. it makes a weird loop but the continuity isn’t affected as much.
