Pasting a range into an email, while also adding text to body and keeping signature

[Apoc]

Hi,
So I am trying to create a script that will copy data from a range of cells on my spread sheet, open up a new email, paste in the range, add some text to the email body and contain my default email signature.

The email should ideally look like:

"Hi
Blablabla example text"

*Pasted range from excel*

Signature

I have worked out how to do most of this with bits of my own knowledge and some helpful tutorials however I cannot seem to get both the pasted range and the text body in the email without it removing my signature. Code so far:

Private Sub CommandButton2_Click()
    Dim OutApp As Object
    Dim OutMail As Object
    Dim wdDoc As Object
    Dim oRng As Object        
    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)    
    Range("B55:L58").Select
    Selection.Copy        
    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)  
    With OutMail
         .Display
         .To = "TestEmailAddress"
         .CC = "TestEmailAddress"
         .BCC = ""
         .Subject = "test"
         Set olInsp = .GetInspector
         Set wdDoc = olInsp.WordEditor
         Set oRng = wdDoc.Range
         oRng.collapse 1
         oRng.Paste
    End With
        End Sub

This works fine for the range + signature, but if I try to add text to the body of the email with .Body or .HTMLBody, it either gets rid of my signature or the excel range. I am too new to VBA to understand why or how to fix this, can anyone assist?
Using Outlook 2016/Excel 2016.
Many thanks,
