It would be really helpful to be able to use a variable to set a Type Style’s Letter Case (under the Type Settings meatball menu).
It could be a String Variable, and the options would be “As entered”, “Uppercase”, “Lowercase”, “Title case”, and “Small caps”.
I personally use modes to switch between different brands, and some brand styles require uppercase while others don’t allow it. This suggestion may be a small feature in the grand scheme, but I wonder if others would also find it useful.
Same here! We also used modes to switch between brands and have the same issue. This solution would be awesome.
Super useful thing while working on different brands as already was mention. We are not going to be able to implement typography variables until this cases are covered 
Same here! Type variables are not suitable for a multi-brand library. Such a bummer!
Voted! We use sentence case on iOS buttons and uppercase on Android buttons.
Agree and voted! I work in-house and our brand uses particular fonts for certain scenarios which are only permitted in caps, not having this is a huge pain for us (so not only for users who may work for different brands!)
Voted! This would be super useful for us, as we are working with a multi brand design system.
VOTED! this is essential for my multi-brand system
This feature is very needed. Any updates on the agenda for this?
Our team really needs this for our multi-brand design system! Are there any updates on this?
I work with multiple brands, some using different cases, this is really needed fast. Do we know if variables improvements are coming soon?
This is an essential feature for our multi brand system. Any updates on the roadmap for this?
Hey All, thanks for the feedback!
We’ll pass this onto our Typography variables team for future consideration.
Thanks. This is our #1 variable need! Much appreciation if you could let the team know how important this need is.
100% needed and voted 
I’m creating a product with multiple modes for brands and some user lowercase buttons, some title case, some all caps-- this would be SO useful. Voted!!
Please please please add this as a feature. As with everyone else, I manage multiple brand themes and need to be able to control case across the themes. The update can’t come soon enough!
+1. Need for multibrand support. Please.
Any update on this @dvaliao? Next couple months possibly? It’s literally just CSS text-transform…
I’ve made do with an incredibly cumbersome and not dev-friendly workaround that is basically a placeholder in hopes that this feature will be launched soon 
yes I really need this for a whitelabel branding solution…
