Area/Zone Selection does not work for //sel poly polygon selections

Describe the solution you'd like
Add a feature that allows to create zones based on the worldedit selected area/blocks

FE zone system is not based not WorldEdit. WorldEdit integration is limited to rectangles only. FE can only support //sel poly if the whole portion of zone selection is rewritten. FE staff is not able at this time to dive into this code to make this happen in a certain time frame. I'm sure you'll figure out the workaround.
