Hello.
We all get a lot of e-maills, and a lot get's lost in our inboxes (even when tagged with triggers and reminders for follow up).
Currently I can request sign off from multiple people with a simple flow from sharepoint folder (3 dots > Request Sign Off > add Assigness (and message)), but it will go as a simple approval flow of the first one to respond gets it done.
I'm trying to create an automation to request multiple assignees sign off of a document hosted in sharepoint in a manner that all must provide approval for the document to be approved. I would like to have this flow created to be used for documents, if possible in a similar quick way (or else it will not be easier to use than a simple e-mail request).
From the template provided in PowerAutomate I have this:

I would like to have a sort of pop-up or request field to add the approvers when activating the flow. Would this be possible?
Also,

If I had a major storage (like a central folder where a lot of other folders/subfolders are held), would the flow be possible to use as long as the file to be approved is somewhere inside?
If I would have to create a new flow from scratch for each document it defeats the purpose of this. The aim is to have a quicker and less prone to error way to request approval of documents from named stakeholders.
