Yes please. Givebutter added a user-editable Contact Since field earlier this year, and it works when importing NEW contacts... but we have thousands of contacts that were imported before the feature was added. They all have wrong Contact Since dates.

I'm really itching to fix that with a newly imported file of just two columns: Givebutter ID and Contact Since.

I'd even settle for a one-time import done behind-the-scenes.

This is really important!
