Hi! and Welcome! And Sorry for the delay.
I believe you need to add this functionality in your script’s with #BSUB directives.
The job composer, as it is, is fairly limited in what options you can change in the UI form. Indeed, it has very few options that you’d want and need (file output location, cores, memory and so on) so most job configurations go in the scripts through scheduler’s directives.
Hope that helps, and again, sorry for the delay.
