When I click on Edit Page in VB for diff pages, will tool create a new local branch everytime ?

Summary

When I click on Edit Page in VB Studio, every time VB tool will create a new local branch or same local branch as I was previously working will be opened?

Say for example If I was working with Personal Details Page, I did an Edit Page in VB, performed some changes but did not save to main branch, Now I closed the tool.

Some time later, I went to Change Assignment page and opened it via Edit Page in VB, will same local branch be opened? If yes, how am I supposed to manage the fact that I want only Change Assignment changes to be saved to main branch but at the same time do not want to lose my work on Personal Details page so that I can come later and continue on those? means how do I manage work done in different sessions?
