Add placeholder to a single choice

Is it possible to add placeholder text to a single choice dropdown in forminator?

Basically the issue that We’re asking people to select an option. But the first option is already selected. So it’s hard for the user to know whether they’ve already filled out the field or not.

In an ideal world there would be a placeholder that says “please select” which would initially be a light grey. Then when you select an option it changes colour or a little tick appears at the end to show you’ve made your choice.
