In Mongoose Traveller 2e, a Plasma Gun does 1DD in damage, i.e. 1d6(d6). The result of the first d6 rolled determines the number of d6 in the second roll; the final damage roll could be 1d6, 2d6, 3d6, 4d6, 5d6 or 6d6. Other weapons may do 2DD - 2d6(d6) - and so on. It would be great if there's a simple formula for this roll, so that I can bang it into the automated script on the character sheet. However, I don't see a way of doing it with the commands/syntax available. Any ideas?
