I'm in the early stages of building a fictitious route.  Obviously, that means adding baseboards as I go.  However, they always add at 0 height.  
Is there any way to either a) add a new baseboard which is all at height n and/or b) add a baseboard at height n with a known gradient - e.g. starts at height n on a given side (say south) an has a uniform gradient of x%?
