Suggestion: Area based chunk loaders

Hello! I am suggesting an additional features to Mythicdungeons, working similarlly to the chunk loader, except working in an area selected. Similar to worldedit, where you click on two corners and those two corners become a region, you could click on two corners and those two corners and all chunks touching them inbetween in a square would be loaded. This is a massive help for larger scale dungeons as placing a chunkloader every chunk is incredibly painful, aswell as mythicmobs persistent despawn variable doesn't work for this application.
