Question : Looping thru 4 sections, changing field codes in headers

With the cursor residing in some section of my document, I would like to perform the following:

- Access the ODD page and EVEN page header of the section where the cursor currently resides in and change the field code {REF bookmark_DE \h} to {REF bookmark_EN \h} using VBA. (That's what the below code is doing)

- The code should THEN GO ON on and loop thru the following 3 (three) sections and change the existing field code {REF bookmark_DE \h} in the even and odd page headers in the following order to ...
{REF bookmark_ES \h}
{REF bookmark_FR \h}
{REF bookmark_IT \h}

I hope this is feasible.

Thank you very much in advance for your help.

Regards, Andreas

Sub ModifyHeaderFields()
    Dim sec As Word.Section
    Dim rng As Word.Range
    Dim fld As Word.Field
    Dim h As Word.WdHeaderFooterIndex
    
    Set rng = Selection.Range
    Set sec = rng.Sections(1)
    For h = wdHeaderFooterPrimary To wdHeaderFooterEvenPages Step 2 'omit first page header
        For Each fld In sec.Headers(h).Range.Fields
            fld.Code.Text = Replace(fld.Code.Text, "REF bookmark_DE \h", "REF bookmark_EN \h")
        Next fld
    Next h
