[PHASER][P2]Easier way of dealing with curvy shapes

[schmevie15]

Hey there,

I was wondering whether there was an easier of dealing with curvy shapes such as the one I have attached. I've done a similar shape that was much smaller using P2 physics and handing in to physics a JSON of smaller rectangles to handle collisions. This took me quite a while though especially to get something that acted smoothly. Is there any way of adding either physics data or drawing this shape with P2 so that it can collide well with other objects? 

Thanks in advance!
