Select Multiple Files And Have Macro Repeat The Process

Im trying to get my macro to open allow me to select multiple workbooks, then have each workbook open up and copy A2:N2 and down and paste these into my active workbook, under each other, ie on the next available row (basically combining all the workbook data together to create a big list.

The below code works to open a single workbook, copy the data and paste it in at the next available row, but I have to keep running the macro for each workbook whos data I need to import!

How can I modify this code so I can select more than one file? I need something like for each wb .....at the end next wb...until the macro has done the below for all selected workbooks.

VB:
Sub openandcopy()

Dim wb As Workbook
Dim ws As Worksheet
Set ws = ActiveSheet
Set wb = Workbooks.Open(Application.GetOpenFilename)

[Code] .....
