Find and replace multiple words in Word

Question

I really hope you guys can help, I feel like I've been struggling with what should be (and probably is) a really simple problem. I've written an app which creates a folder structure, copies in the relevant test documents based on user inputs, and populates the document header and test sheets with various variables. I have populated the template test documents with placeholders, ("replCustNo","replPrjNo","replCustRef" etc), some in the header, some in the body of the document. I can only seem to replace one word at a time, I can't find a way of listing all the references to find, then listing all the replacement variables. Seems like a very clumsy way of coding to have the find/replace over and over, or call on a sub for it.

Forgive me if this is really basic, I'm very new to coding, I'd really appreciate some help! I'm using vb and office 365

 Dim objWordApp As New Word.Application
    'Open an existing document.  
    Dim objDoc As Word.Document = objWordApp.Documents.Open(projFolder & "SAT\2 HV Tests\Flash.doc")

    objWordApp.ActiveDocument.Sections(1).Headers(1).Range.Select()
    objWordApp.Selection.WholeStory()
    With objWordApp.Selection.Find
        .Text = "replPrjNo"
        .Replacement.Text = RefNo
        .Forward = True
    End With
    objWordApp.Selection.Find.Execute(Replace:=Word.WdReplace.wdReplaceAll)

    'Save and close the document  
    objDoc.Save()
    objDoc.Close()
    objDoc = Nothing
    objWordApp.Quit()
    objWordApp = Nothing

One solution can be with document variables. Select a placeholder in the template document and then Insert tab > Quick Parts > Field... > DocVariable > New name: replPrjNo

Then in the code:

objDoc.Variables("replPrjNo").Value = RefNo
objDoc.Fields.Update

Other solutions can be bookmarks, custom document properties, Mail Merge, or some of the controls in the Developer tab.
