I used to work at PTC and know that there is a way to run trailfiles from a command line with no graphics window. It might take a while to get it to work properly but if you open wildfire and hit open and type the direct file path and generate a BOM and then close the window or erase all from current you should be able to create a trailfile that you can reuse by replacing the file name in the trail.txt. file and reuse.
Use spaces between the 4 as shown in example below.
startup_command run_mode graphics_mode 1 trail_name.txt
wildfire.bat 1 0 1 bom_trail.txt
the command may run without the .bat or .exe depending on your computer settings
1 is the default run mode
0 is selects no graphics be displayed
1 the second 1 is used to tell Pro/E you want to run a trail
Graphics modes
0 No Graphics
7 Open GL
8 X-Windows
9 Win_GDI
Give it a shot and let me know if it works!
If it does you'd just need to have a txt document with Assembly or Drawing name to open like draw01.drw, draw2.drw that you could replace and save to a new trail file.
You should be able to put multiple names in the trail file and run trails with simultaneous copies of the lines from your original trail.
