multiple dev and one prod deployment pipelines

Hello!

I'm new to deployment pipelines and I can't find the answer in the documentation. 

If Ihave 5 workspaces of a business unit, is there a way to create one pipeline for all of this workspaces?

what I want to do is to have only one production workspace that is based on those 5 dev workspaces. Is this possible? if it's not, is there any other way to work this?

I want to do this because in every workspace I have different users developing reports, from each workspace there are only 1-2 reports that I want to take to production, so because all of theese workspaces are from the same business unit, I would like to leave them in only one production workspace instead of creating a production workspace for each one. Also having multiple production workspaces seems to be harder to manage. 

Thanks!
