Referencing a filw in Workdrive

Referencing a filw in Workdrive

Hi,

I'm building a form where the user will need to reference (not upload) documents hosted in our workdrive.
I thought about using the Upload field, but this would copy the document from workdrive to Creator. Not reference it (is permalink it)

Using an URL field, doesn't allow browsing Workdrive for the file.

How can I let the user browse Workdrive and when the document is selected, it's permalink or Document URL is saved in creator ?

Regards
