How to make a Contact Property automatically fill in capital letters when details are entered?

[#1]

In the Property Settings, Contact Information I want to be able to set properties like 'CITY' and 'State/Region' to automatically be typed in as CAPITAL letters, as this is the format all contact details have been entered.   This is to avoid anyone fillng out a form, to use lower case when fillng out these sections on a form.

Is this possible?  If not, can it be created as a function?

Hi @JenP 

I would recommend upvoting this idea as a starting point. 

Additionally, it looks like someone came up with a similar solution for capitalizing names that may be a good starting point for what you are looking for.

Thanks,
Jenny
