Success and Failure visible

[Eligor]

hi, i was wondering if there is a way to show the player success and failure on attack/challenge roll without showing the real number.
for context:

here you can see Ruru (the player), attacking the Lizardman both with a success and a failure. The player won't know the real number, but he know the results.
on the other side, we have the GM roll of the Lizardman attacking Ruru, i know that it's a success, but the player won't know that. I would like to show them the final result, but without showing again the real number, so they have to figure it out. So is it possible to add a System option to enable something like that? so show the "success/failure" like the challenge roll, or just the green/red outline?

Thanks for the answer, and keep up ur work, u're amazing!
