This post , mentioned by @Grade, tried to remove the named watermark (trying to use the term here), but was only slightly successful with this macro:
Sub Hide_Names() Dim iName As Name For Each iName In ThisWorkbook.Names iName.Visible = False Next iName End Sub
This topic here (the same forum) since 2002 tried to answer your question, but did not answer ... what does this function mean in Excel 2000 and is still poorly documented.
I just looked through all the Excel objects and Interop libraries for the name, scaling, and watermark and did not find anything similar to this function. I hope someone smarter can shed some light, but I think your answer is simply no.
