InfoPath Dev

Ideally, I would like to add these items to the drop down list using the refresh button ...

Hello, I have a similar issue with this. I have my property promotion fields as "merged," but it doesn't work well when reporting in SharePoint. Is there a better/easy method (i.e., SQL) that I can use to resolve and improve upon this issue? Thanks, in advance for your help.
