I feel your pain the information for knowing this is so terrible i spent a week looking into how this is done.

In the command line.

I believe its -mod/"ID,ID,ID,ID/" ( steam keeps auto changing this use example below )

EX ( this is mine in my command line )
-mod=\"3331511657,3325592770,3350049311\"

Thank you so much for taking the time.

This worked for me.
