Yes, I did think about it through the editor, because the editor can handle everything automatically. 
But for some cases it involves merging through p4, such as robomerge tool, which can automatically merge between branches. So I hope to be able to complete this process automatically. A VA graph can indeed achieve consistency, but it is a last resort. However, I’ll have a try in this way.
If there is a good solution someday, please let me know.
