Zoom In On Map / Crop Map

Customizable Art for maps has it's own community, or has been attempted but failed do to the large task it takes to completely fill it in. Imagine if you could use a cartography table and grab a slider that will zoom the map in to crop it in some way. I believe it would only be able to be zoomed in as making a larger map still would have to be possible within the cartography table the way it was originally added. I just believe it would push more players to attempt map art if they did not have to attempt to fill in a huge area to get a small picture.
