Allowing multiple file input into Geodetic List Conversion would allow the user to convert their whole project at once instead of running each XYZ through one at a time. It could have an "append to file name" entry option like saving in SBMAX64 or MBMAX64. Alternatively, giving more options in export for customizing the XYZ output to allow different options for expressing latitude and longitude (ddd mm ss.sss, ddd.ddddddd, etc). and depth conversion options (from feet to meters, from meters to feet, etc.) like is available in Geodetic List Conversion.
The lat-long convention, I believe, is dependent on what convention is set in the Shell. The unit conversions can be done with Project Conversion.
