Hi Kyle,
I'm not sure what you mean by "...which will pop file upload...".
Do you want to open a window to the location where files should be uploaded (Dropbox, SharePoint, etc.)?
Depending on how specific you need to get you can just paste the appropriate ULR into URL field.
If you need the URL to change based on another folder that identifies which location you can do that using the Formula URL field and the CASE formula.
However, if you need to open a specific file path within the designated location that's a little bit trickier, but doable as well.
If you can provide more details on what you're looking to do, I'll try to help.
