In order to add files that are in a package to a transmittal currently, you have to open the package, select all of the files, then you can add those files to the transmittal. So in essence you are adding the package to the transmittal, but not really. I want to add it as a package. As one entity. Makes it simpler and also ensures a slip of the wrist doesn't remove something.
If I'm wrong on something here, and it is currently possible, please let me know. Thank you.
