EILIndoorLocationView Map Customisations

I have a question regarding how to customise the SDK map.
I want to be able to;
Map connecting rooms - can this be accomplished in one map, or must I display two (or more) adjacent maps?
Add custom colours - is it possible to use any colour for walls and doors (such as UIColor), or only those colours in the SDK?
Allow users to zoom and pan in the map - can this be accomplished in the map, or must the locationView be wrapped in a UIScrollView, and the scale manipulated to suit?
