Create Hierarchy Relationship using WBS and Formula?

Hi, 

I believe this may be a bit of a stretch but I am wondering if it is possible to automatically create the Child/Parent relationship utilizing the numbers or periods in a WBS # column as a way to automatically create the indention.

I have built a pretty good process using Smartsheets data uploader to import external timelines and compare regular updates against baseline.  Utilizing the Unique ID and WBS fields in MS Project I am able to ensure the correct task is being updated and the order is maintained in Smartsheet.

It would be really nice though if I could recreate the hierarchy automatically from the MS Project file in my Smartsheet through this process.
