Data Shuttle Update Rows Workflow: Preventing Duplicate Updates

Hi all,

I have a data shuttle update workflow that runs on a schedule updating rows in the target Smartsheet as they change in an excel source file stored in Box. I wanted to see if there was a way to somehow configure the data shuttle workflow so once a row has been updated, it can't be changed again. I tried doing this by automating rows so they locked once modified, but data shuttle seemed to still update locked rows. Any suggestions/thoughts would be greatly appreciated, thanks!
