Characters in Rise scenario block

I work in the mining industry and would like to use scenarios more in our courses, however the characters available in the scenario block aren't suitable. I know there are some under 'industry' wearing basic PPE, but from a mining perspective, the PPE isn't adequate. Can characters be added wearing full hi-vis shirts, safety glasses and hard hats please? The full hi-vis long sleeve shirt is key. Current characters have hi-vis vest which makes them look like a visitor to a site, not a worker.
