setting mapping defaults at system level

I am trying to use maps at the system level, the view where it shows a dot for each project in the database. I have three related questions I cannot find answers to.

When I go to the Mapping menu item and press "Open Map" in the ribbon, the map opens and it seems that I can save the zoom level and extents by pressing "Set Initial View" from the ribbon in the Map Tools menu item.

When the map opens, the legend/sidebar of the map has the project symbol coded by Status. There is an option to select Category that is off by default. I prefer Category to Status, but after I make the changes I do not see where I can save that as a preference. "Set Initial View" does nothing in this regard. The image below shows what I

Q1: Where can I set the default legend/sidebar settings for the map?

Further, when I zoom in toward project locations, there is no label (Project ID) until I get to zoom Level 7. This is too close and I would like to see that information at a wider view.

Q2: Where can I set the zoom level at which the project label appears?

I am aware that I can use the tooltip to click on the project symbol and a popover with some relevant data will appear. While this is potentially useful, it is not nearly as useful as seeing Project ID at a wider zoom level.

Q3: Where can I edit the tooltip setting for the system level map?

I have found where to set these preferences at the project level -- in the Configuration Pack, from "Default Locations" in the Mapping section of the ribbon, but I cannot find it for the system level.

Thanks
