Edit context from-did-direct

Hi,

I use freepbx 2.11 with asterisk 11.5.1. I want to edit context from-did-direct, but if I put from-did-direct-custom in extension-custom.conf nothing appens.
I also tried to put as last line this:

[from-did-direct-custom]
exten => …something
exten => _X.,n,Goto(from-did-direct,${EXTEN},1)

but without succes.
Can anyone tell me where I’m wrong?
Thank you

The file:
/etc/asterisk/extensions_override_freepbx.conf
exists so that users can redefine existing freepbx contexts. Copy the entire [from-did-direct] context into this file, make your changes, save and reload the dialplan. You can confirm your changes are enabled at the Asterisk CLI with the command:
dialplan show from-did-direct

Thank you!!
