I have an AWS VPC with route table attached. I would like to add a route to the route table.  
Using ec2\_vpc\_route\_table module I do  
routes:  
-dest:   
-gateway\_id: igw

Checking in either aws console or via ec2\_vpc\_route\_table\_facts  
I see that a new route table has been created with just this new route instead of modifying my old route table.

From what I could gather on the internet this functionality may not be supported and I would have to do entire route table delete/add  
which seems like a very intrusive way of doing things.

Also, main route table addition may not be supported.
