• I agree to follow the Code of Conduct.
• I have searched for existing issues that already include this feature request, without success.

Describe the Feature Request

It would be useful to be able to style the internal wheel picker for ion-datetime, maybe by being able to forward a class list to the inner component.

Describe the Use Case

I have a month picker for which I'm trying to style the month labels, as Intl.DateTime provides italian and other months with all lowercase labels and I need them to be capitalized to standardize the experience between languages. It was previously possible in Ionic <6, as the label list could be provided separately, so it is technically a fix for a regression.

I just found this issue #25945, my use case is slightly different, but since it would satisfy my need I leave up to you to close this issue as duplicate.

Thanks! I will merge the two threads, but we will be sure to consider both use cases if this feature gets implemented.
