Backlog Aging Report

[Nathalie Kapuya]

Hi 

Wondering if anyone has tried to solve for this scenario:

I manage backlog portfolio items in a list using x number of tags aligned to the various stages of my process(e.g. Stage 1, Stage 2, Stage 3)

I would like to get insights of how many days a particular portfolio item has spent in an individual stage such as: 

• Feature 1 - Stage 1 - 10 days
• Feature 1 - Stage 2 - 20 days  

I had a go at using a query filter on the Tags, however could only report on the Name and Archived attributes. 

Appreciate all the suggestions. 

Thanks!
