Custom Character Sheet - translation.json combining elements for reuse?

Does roll20 support a version of JSON { "key1": "hello", "key2": "world", "key3": "$t(key1) $t(key2)" } I have a talent tree and it has prerequisites like 'this talent OR this other talent."   I already have data-i18n elements for the name of those talents and was hoping to not have to maintain the talent name in two separate data-i18n elements. That way I could re-use the existing ones so I could display the prerequisite names in a tool-tip or separate column and if I have to update the name, I only update it in one element.

No, but that sort of combination could just be done via HTML. E.g. just use two spans that have the same i18n key as you use elsewhere.

That is 100% the correct answer for what I needed and thank you for providing it. My brain was so stuck on combining the elements I didn't step back and reassess what I was trying to accomplish and how to solve it.
