Precisely align actors in viewport

I am trying to align an actor to another actor very precisely. But when I zoom in, I can no longer see widget to move the actor, I have not found a way to move the actor without clicking on its widget…am I missing something? I tried seperating viewport into 4 views, but zoomin one view zooms all views so I am unable to set one to see and click on widget while I use other to visualize placment?
