@brakcounty Ok so what I gather here is SCCM creates a single boot image for task sequence (actually there is probably just a text file that calls out the task sequence number). Where as MDT boots into the mdt menu where you can pick the task sequence you can boot. If you look deep into the code its probably the same logic just one has a menu and the other no.
All of that can be automated into a batch script to take the files, edit the boot.wim and do what is needed.
From the “Publish the boot files” you can have FOG take over here. With a properly crafted batch file you can cut out a lot of steps.
