Workato/Wrike Integrate - Upload attachment as SharePoint link

Hi There,

I'm working on a recipe that is nearly doing what I want it to, but I'm falling at the last hurdle.  My recipe creates a SharePoint folder structure and copies in a document template, all named according to company naming conventions.  That's all working really well.  I then want to upload the document into the project header in Wrike.  This is the part that's nearly working.  I need it to be uploaded as a SharePoint link, rather than as a native file.  Has anyone achieved this before?  

I realise I might be butting up against what Workato/Wrike Integrate (what is the right name?) can do, but I'd love to know if this is possible.

Thanks!

Phil
