Hi Ken, If you are referencing the D&D 5e 2024 by Roll20 character sheet then you can add multiple sources of damage to a single attack roll by switching to the Compact view and editing the attack. The Statblock method of editing is intended to be simple, although I *think* the Devs might be considering changing it so that two sources of damage can be added via that method of editing. As for rolling damage without an attack, I think the sheet is capable of this via effects, spells, etc but it is not yet "user facing". You might try finding an existing version of that and then re-working it for your purposes.
