How to retard timing when shifting with AEM EMS

[TucsonTSI]

Does anyone know how to set up the AEM EMS to retard timing during shifts? Is is possible to do so without having the AEM control the shifting itself? I can see that Kiggly has set us car up to do it, but I think he has the AEM controlling shifts too. I'm hoping there is a way to reduce timing when the motor is dropping rpms. Is there a way to do that?
