How can I make a custom field mandatory only in a transition screen?

[Felipe Perez-Young]

I added a custom field to the issue resolution transition screen and made it mandatory. But now I can't create new ones because the issue creation screen asks for it even though it's not visible. In addition, that field does not apply or make sense at the time of creating the issue, only at the end when it is resolved, and I need it to be filled only at that moment. How can I make the field mandatory only on the resolution screen?
