Is it possible to update the "standard" base layer?

I'm very new to this. I have used Street Complete to do some little things over the last few months, but made my first manual edits yesterday.

I'm starting by fixing up the small community where I live. A lot of stuff has already been done by some automation using "NRCan-CanVec-7.0" data and it's really wrong for civic numbers. But, it matches the numbers in the "standard" layer in the maps. I'm happy to go around and manually draw houses and update civic numbers (I did say it's a small community) but the map is going to look confusing when the base layer shows conflicting numbers. How can I fix that?
