Currently, buddy lasing is possible to do but its kind of janky. You can drop your buddy's weapon on its set laser code, but if you're trying to do an engagement where you're also lasing in a separate munition, you then have to hurry up and mash in the second laser code for the other munition.
Since most aircraft have a SMS page for weapons of sorts, it would be great if we could set an individual laser code per munition and even select which station we will be dropping the weapons for as to avoid employing the wrong weapon.
The example in mind is for an engagement with 2x GBU-12s
You have 1 coded to 1111 (your laser) and 1 coded to 1112 (the buddy) then, select those two specifically and drop them both in the same engagement pass.
