OK, this has all worked exactly-ish as I had hopped.    I made a copy of the official Roll20 API supported SW html, css and translation.  I edited the html to add a few sections, tested them, and they work. (I basically just copied the code from a different sheet)   <optgroup label="Magic Skills">
    <option value="!eed rollPlayer(character:@{name}|skill:intellect,rankArcana) label(skill:Force Power|Skill Name: Arcana|Power Name:@{forcepowername}) @{ForceSkillDice} @{forceavailable}w @{dicePool} (gmdice)" data-i18n="arcana">Arcana</option>
    <option value="!eed rollPlayer(character:@{name}|skill:willpower,rankDivine) label(skill:Force Power|Skill Name: Divine|Power Name:@{forcepowername}) @{ForceSkillDice} @{forceavailable}w @{dicePool} (gmdice)" data-i18n="divine">Divine</option>
    <option value="!eed rollPlayer(character:@{name}|skill:cunning,rankPrimal) label(skill:Force Power|Skill Name: Primal|Power Name:@{forcepowername}) @{ForceSkillDice} @{forceavailable}w @{dicePool} (gmdice)" data-i18n="primal">Primal</option>
</optgroup>    Added the needed translation info as well.  	"magic-skills-list": "arcana,divine,primal",
	"arc": "Arc",
	"arcana": "Technomancy",
	"Arcana": "Technomancy",
	"arcanaint": "Technomancy (Int)",
	"Arcanaint": "Technomancy (Int)",
	"primal": "Primal",
	"Primal": "Primal",
	"primalcun": "Primal (Cun)",
	"Primalcun": "Primal (Cun)",
	"divine": "Mystic",
	"Divine": "Mystic",
	"divinewill": "Mystic (Will)",
	"Divinewill": "Mystic (Will)",
	"magicskills": "Magic Skills",   and so on...  The issue however is that if I edit the translation file to change "wording" i.e. switch arcana "Arcana" to arcana "Mystic" it works, but only in 95% of the locations.  The dice boxes look good for almost all occasions, but the Force Powers skills I included above.  Those three lines never change wording.  You'll notice in the images, it shows my "new" Mystic  Skill List  wording...     but in the dice box,  Skill Name , regardless of what I do, it still says Divine, or Arcana, etc.      I've tried to manually edit the words, but if I do, then the box fails to work.  Ideas?
