How to set up external trigger for conversion

Thank you for setting up this library! I would like to trigger the output of the DAC based on an external trigger. According to the docs of the arduino giga (https://docs.arduino.cc/tutorials/giga-r1-wifi/cheat-sheet/?queryID=37005a6b50265e10fe098d0af5a53c7f), this should be possible, it states "External triggers for conversion". Is there a way to do this with the AdvancedAnalog library?
