Uppercase a text field

I am creating a database table maintenance screen and would like the “Id” field to always be capitalized. I tinkered with the mask feature
, this capitalizes the letter entered but this only allows a single character. I changed the mask to read
and this gave me the following “MYID______”.

Any ideas on how to make the mask work for variable lengths using the platform?

you can find example and demo of such a transformation to upper-case here: https://www.cuba-platform.com/discuss/t/auto-caps-lock-or-uppercase-for-user-input-in-screen#comment-1055
