Pasting Multiple Entries into Multiple Selection Select Option Box

Hello WDA experts,

We have a simple requirement to paste a few value entries (e.g. materials) from the clipboard into a Web Dynpro Multiple Selection box of a Select Option (implemented by way of Component WDR_SELECT_OPTIONS), whereby each entry is pasted into a different row.  Sadly, only the first value (of several on the clipboard) is pasted into the Web Dynpro Multiple Selection popup.

Material values on the clipboard:

Web Dynpro ABAP Multiple Selection:

This works beautifully in a classic SAPGUI ABAP Dynpro Multiple Selection box.  Each entry is successfully copied to the respective row.

Do you have any suggestions on how to make this work for Web Dynpro Multiple Selections?

Best regards,

David
