Highlight cells before checking if the cell is empty & send email

I have the following macro run when I click on a button.

Option Explicit
Sub DontRunUtil_Override()
    With Worksheets("TSA Request") 'Change CodeName to suit
        If IsEmpty(.Range("F31")) Then
            MsgBox "Missing Local or IF Type", vbCritical
            Application.Goto .Range("F31")
        ElseIf IsEmpty(.Range("F17")) Then
            MsgBox "Missing Location", vbCritical
            Application.Goto .Range("F17")
        ElseIf IsEmpty(.Range("F20")) Then
            MsgBox "Missing Customer's Name", vbCritical
            Application.Goto .Range("F20")
        ElseIf IsEmpty(.Range("F4")) Then
            MsgBox "Missing Customer's ID Number", vbCritical
            Application.Goto .Range("F4")
        ElseIf IsEmpty(.Range("F5")) Then
            MsgBox "Missing Customer's Order Number", vbCritical
            Application.Goto .Range("F5")
        ElseIf IsEmpty(.Range("F6")) Then
            MsgBox "Missing Container Number", vbCritical
            Application.Goto .Range("F6")
        ElseIf IsEmpty(.Range("F9")) Then
            MsgBox "Missing To Address", vbCritical
            Application.Goto .Range("F9")
        ElseIf IsEmpty(.Range("F10")) Then
            MsgBox "Missing From Address", vbCritical
            Application.Goto .Range("F10")
        ElseIf IsEmpty(.Range("F7")) Then
            MsgBox "Missing Type of Service Requested", vbCritical
            Application.Goto .Range("F7")
        ElseIf IsEmpty(.Range("F8")) Then
            MsgBox "Missing Date Requested", vbCritical
            Application.Goto .Range("F8")
            
      Else
           Run "Module6.Mail_Sheet_Outlook_Body"
        End If
    End With
        
End Sub

I would like when i click on the button for it to highlight those cells to inform the agent which cells need to have data in it and if it is all filled out properly then run this macro. Any help would be greatly appreciated - I have included my workbook for any assistance you can provide!
