Drag and drop activity

Hi everybody,
I have created a drag & drop activity that could be useful for teaching languages, here is the link:
Trialx99 | Bubble Editor

Being an absolute beginner with Bubble, I found a way to do it by just fiddling around. The problem is that for every single drag/drop element, I had to create another one and then put in the workflow that when a drop area has a Drag/drop group dropped on it, then another Drag/Drop group will go there (please see workflow for better understanding). if I want to create a bank of sentences, the process would be far too long, I was wondering whether there is a faster way to get the same result without needing to do what I did?
Many thanks
