  I am developing my Security Group for a VPC that has my Elasticbeanstalk, RDS and ElastiCache services and I am at this dashboard:
  
  [![enter image description here](https://i.sstatic.net/4wnsF.png)](https://i.sstatic.net/4wnsF.png)
  
  Under **Source**, it used to be that you could select `sg-0x12345-my-application`, but now it only gives you the option of **Custom**, **Anywhere** or **MyIP** and I am not sure which one is the equivalent to selecting the security group for the architecture I am building this SG for.
