Why isn't there an option for sequential routing?

Hey!

My workflow is the following:

I have opened another thread because that is another solution.

But basically I want to read data from Airtable fields, upload them to S3, get the root folder and send it through a webhook in integromat for it to be processed and after a small wait period continue to finish this up. The problem I had was receiving 8 output items so I send 8 http requests to Integromat instead of 1 with the folder name and that is it. So I tried trimming and opened the other thread, the other thing is to just put the http request on a separate route:

But n8n does not process items in a sequential route after route basis, it just zigs zags through every route simultaneously from node to node, so this is also not possible.
