Hi arbangalore,
You have such option in the version u specified.
Go to placement edit. In the find filter select only symbols.
select all the components that you already have done the grouping(one path) and right click select done.Also follow the instructions in the command window.
It will ask you to pick origin.Select any location. A window will get opened to save the placement replicate file ,give a name and save in your location.
After that select all other components that you want to place as same as you have done manually.
Right click and select placement replicate apply, a window will open. Select the placement replicate file that you already saved.
All will get grouped as you done. Try it. Even you can replicate the routing too...
