ViVa: Modifying Various Graph Properties

I'd like to modify several ViVa (IC6.1.8-64b.500.29) settings related to the appearance of graphs:

1. Is there a way to remove the number that appears on the top right of every graph ("1" in the attached PDF sample graph)? This number is, in most cases, useless and just clutters things up.
2. Is there a way to change the default "Marker Significant Digits" setting from "auto" to "manual" with 3 significant digits?
3. Legends and marker areas are transparent such that the grid is visible (see attached PDF sample graph). I'd find the graph less busy and thus easier to read if those areas were solid white, hiding the grid. Is there a way to achieve this?
4. When choosing "Legend Position" as "Inside", the legend always appears on the top right. In many cases, however, it would be beneficial to choose another location, for example top left. Is there a way to change this?

Thanks very much for your input on these topics.
