Not sure if I follow correctly, but if you just need the count all the types at the end of the workflow you can probably achieve that with a Merge and Summarize node or even the Compare Datasets node.
You could also make that a sub-workflow that will “report” the numbers back to the parent workflow where you create your report.
Let me know if that makes sense? You can also share your workflow here for better context.
Tip for sharing your workflow in the forum
Pasting your n8n workflow
Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.
```
<your workflow>
```
Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!
