macOS Applescript Import Into Address Book - A Better Way?

[Bonusgrabber]

I have written an applescript that uses the export from Filemaker to import into Address Book.

The script adds a header file to the exported file first. (Not a problem there)

The script then calls Address Book and does a click menu item to open the Import dialog (Not a problem there)

Selecting the folder and filename works but I am sure there is a better way to do it. Here is the code:

set importpath to "/Users/TWK/Documents/Import/"
set headerfilepath to "/Users/TWK/Documents/System/"
set AddressBookImportFileName to "AddressBookImportNew2.csv"

-- Run cat in shell to add headers to import file
do shell script "/bin/cat '" & headerfilepath & "Headers For Filemaker Export From Address Book.txt' '" & importpath & "Filemaker Export From Address Book.csv' >'" & importpath & AddressBookImportFileName & "'"

tell application "Address Book" to activate

tell application "System Events"
	tell application process "Address Book"
		-- Open Import File Dialog in Address Book
		click menu item "Import…" of menu 1 of menu bar item "File" of menu bar 1
		
		-- Open Goto Folder Dialog and Enter Import Path
		-- Is there a better way to do this?
		keystroke "g" using {shift down, command down}
		keystroke importpath
		delay 1
		keystroke return
		delay 3
		
		-- Type In Import Filename to Select it
		-- Is there a better way to do this?
		keystroke AddressBookImportFileName
		delay 3
		keystroke return
		delay 1
		keystroke return
		
	end tell
end tell
