With regards to the comp/con .lcp file, may I request that you add the recommended triggers to the backgrounds? For example under mil-spec pilot, it doesn't recommend anything.
That was something I checked when creating the LCP but it's not a supported feature in COMP/CON as far as I can tell. From what I've seen suggested triggers aren't on any of the core backgrounds and it's not a field that's documented on the github or included in the LCP editor.
That said, I'll check in with the COMP/CON devs and see if I'm missing a way to add that, or if there are plans to add support for it in the future.
EDIT: Looks like this is not a feature that's planned to be added any time soon, but if anyone desperately wants this to be a thing, COMP/CON does accept pull requests!
An update to this: I'm now working on Shadow of the Wolf for Massif, which (assuming no issues arise during playtesting) will also contain new backgrounds. I remembered your comment and I have put in a feature request for COMP/CON to handle this specific issue, as I agree it would be a great addition. If it gets implemented for first party content, I should then be able to come back and add it for Legionnaire as well!
