You can try the following. When you adding the pdf reference link in Excel sheet then try to add the #page=[page number] at the end of the link. So when you click it, it will take you that page only. Or else there is a code which can help you. Try the below vbcode.
Dim myLink As String
Dim TargetPage As Double
Dim objIE As New xxxbrowsernamexxx
myLink = "locationoffile/nameofile.extension"
TargetPage = anypagenumber
.Navigate myLink & "#page=" & TargetPage
.Visible = True
