Adding an account code when dialing our gateway

General Help
1

Our Asterisk system supports more than one companies. Our Gateway Provider can bill each company based on an Account Code sent out with the Dial. I used the CDR Account Code and did a little patch to the [macro-dialout-trunk] to send the gateway AcccodeDialednumber. This has been working great until I decided to use a newer version. I patched [macro-dialout-trunk] to do this.
[macro-dialout-trunk] is no longer in extensions.conf and has moved to extensions_additional.conf where one cannot edit it.
Any ideas or suggestions on where else to do this?

Here is the code in the older version I added to /etc/asterisk/extensions.conf under [macro-dialout-trunk] as follows:

; Special mod for custom account code
exten => s,n,Set(CODE=${CDR(accountcode)})
…
exten => s,n,GotoIf($["${custom}" = “AMP”]?customtrunk)
; Modifyed next line
;exten => s,n,Dial(${OUT_${DIAL_TRUNK}}/${OUTNUM},300,${DIAL_TRUNK_OPTIONS}) ; Regular Trunk Dial
exten => s,n,Dial(${OUT_${DIAL_TRUNK}}/${CODE}${OUTNUM},300,${DIAL_TRUNK_OPTIONS}) ; Regular Trunk Dial w/ Account Code
exten => s,n,Goto(s-${DIALSTATUS},1)

Thanks in advance for the help…

New version added [macro-dialout-trunk-predial-hook], it is just before the dial happens.

So I added the following in extensions in the [macro-dialout-trunk-predial-hook]

; Special mod for custom account code
exten => s,1,Set(OUTNUM=${CDR(accountcode)}${OUTNUM})

Works great.

Left it here just in case someone else finds a similar situation and need help.
