change viewport window

Is it way to change window of viewport using shortcuts?
I found some commands (top view, left view...)but they just change view in ONE window from top to left etc. So when I back to custom view it looks like previous but in perspective. I need something to change windows not view in one window.

I may not understand what you are asking for, but I will suggest you have a look at :- "Edit > Preference" > "Options" > There is an option for "Custom/Front/Back.. View has own Camera settings"

With that option enabled, each view (front/back etc) will act as its own viewport, retaining its view when switching between them.

Thank you! It was what I looked for
