Possible To Generate Gift Certifcate Codes From Another Source?


I'm busy with an integration for a client and they have a centralised gift code system which they want to use for all gift certificate codes. Is there a way I can use the existing gift certificate add-on but integrate into the centralised system to bring in gift certificate codes instead of being generated from CS Cart?

I have looked at the gift certificate func.php but can't locate how or where the codes are generated from in order to override or look at another source.
