Find cell(s) with certain text and add hyperlinks in a loop - excel

Question

tldr: Find cell(s) with part number xxxxx and add hyperlink to drawing on server.
We have a spreadsheet containing part numbers across multiple columns & rows. Our requirement is to add a hyperlink to parts' drawing, stored on our server. We have tried highlighting them as a group, but get the error
this can't be done on multiple range selection
We also want to keep the comment information intact, just to complicate it further.
Is there code we can use to search for part number xxxxx & add a hyperlink, then find the next cell and repeat the process?
We have found a "find all" code which highlights the cells, just need some help with the hyperlink issue.
Sub FindAll()
Dim fnd As String, FirstFound As String
Dim FoundCell As Range, rng As Range
Dim myRange As Range, LastCell As Range
'What value do you want to find (must be in string form)?
fnd = "70005"
Set myRange = ActiveSheet.UsedRange
Set LastCell = myRange.Cells(myRange.Cells.Count)
Set FoundCell = myRange.Find(what:=fnd, after:=LastCell)
'Test to see if anything was found
If Not FoundCell Is Nothing Then
FirstFound = FoundCell.Address
Else
GoTo NothingFound
End If
Set rng = FoundCell
'Loop until cycled through all unique finds
Do Until FoundCell Is Nothing
'Find next cell with fnd value
Set FoundCell = myRange.FindNext(after:=FoundCell)
'Add found cell to rng range variable
Set rng = Union(rng, FoundCell)
'Test to see if cycled through to first found cell
If FoundCell.Address = FirstFound Then Exit Do
Loop
'Select Cells Containing Find Value
rng.Select
Exit Sub
'Error Handler
NothingFound:
MsgBox "No values were found in this worksheet"
End Sub

Your method can be simplified a bit. My suggestion is to create a function that will add your hyperlinks to any given area.
My test data is
Option Explicit
Sub test()
Dim linkCount As Long
linkCount = AddHyperLinkTo(FindArea:=Sheet1.UsedRange, _
FindThis:="red", _
Link:="https://google.com")
Debug.Print "found: " & linkCount
End Sub
Function AddHyperLinkTo(ByRef FindArea As Range, _
ByVal FindThis As Variant, _
ByVal Link As String) As Long
Dim numberFound As Long
Dim parentWS As Worksheet
Set parentWS = FindArea.Parent
Dim firstFind As Range
Dim findResult As Range
Set findResult = FindArea.Find(What:=FindThis, LookIn:=xlValues)
Set firstFind = findResult
Do Until findResult Is Nothing
parentWS.Hyperlinks.Add Anchor:=findResult, Address:=Link
numberFound = numberFound + 1
Set findResult = FindArea.Find(What:=FindThis, LookIn:=xlValues, After:=findResult)
If findResult.Address = firstFind.Address Then
Exit Do
End If
Loop
AddHyperLinkTo = numberFound
End Function
