I was very excited to receive this product, and was looking forward to canning tomatoes etc. only to find it does not fit the meat grinder attachment I already have. On the box when you have it, it says not compatible, but I did not see that befoire 
So can you buy the KSMFGA attachment Seperately? I do not use the meat grinder anymore, so would like just the attachemnt so I can strainer my tomatoes!
