Hey @Devdatta D, when you create an A-connection from a conveyor to another fixed resource, it automatically creates an ExitTransfer relative to the location of the fixed resource it is going to. Here's a post that explains it a bit more.
If you want to move ExitTransfers to different locations, then you can try following this post's instructions. Or if you want to get a reference to one, try this post.
As for creating new ExitTransfers, you'll need to ensure that whatever the transfer is connecting to is far enough away from the existing "default" transfer that a new one will need to be made.
For example, this may be too close:

while this is fine:

Notice the differences in Sink2's position. The same code was used, but one made an ExitTransfer2 while the other just used the existing one.
