How to use Change Source data in workflows and reports

[LMC-Alex]

I'm trying to figure out how I can use property "change source" information in workflows and/or reporting (see screenshot).

My use case:
We have a number of different ways of updating data: 
1. Manual
2. Workflow
3. Data import

Our manual data is more reliable than the data we set via workflows and imports.

I want to:
a) Prevent workflows from overwriting manual data, whilst allowing them to overwrite data set by workflows or imports.
b) View which source data came from at scale within Hubspot, without having to export property history and work with an excel.

Any ideas?

Thanks!

Maybe the drill down 1 / 2 source propeties will help? @LMC-Alex 

The following table shows the Original Traffic Source or Latest Traffic Source values and the possible Traffic Source Drill-Down values included in each category:

Hi Levi,

Thanks for your suggestion. Unfortunately that's not going to help here as these fields don't show me who (or what) was the last person (or workflow/import) to update specific properties.
