Reveal Roll to Players with Click?

Hey all, Putting together some Westend Star Wars D6 templates for NPCs. I was wondering, is there a way to make it so that the results of an NPC's roll are not available to see to the players till I click on them? I want them to really think about using character points for extra rolls if they roll low. That way they don't exactly know how many they need to use to beat my roll.

No amount of code, api, or screenshots is going to fix that problem.  Just hide the roll and tell the players what you rolled after.  The underlying problem is a trust level between the GM and the player.  I honestly will just not invite low trust players back to the table if it becomes annoying when they question the rolls constantly.  I have a player who believes I can edit the quantum roller.  You just can't do anything thats going to change those folks.  

Well, the folks I play with are family and friends I've had for decades, so thankfully trust isn't an issue :) Was just hoping. Thank you the answer!

Maybe you could screencap your gm-only rolls and post to chat if needed.

OH! that's actually a fantastic idea! Especially when fighting bosses. I am going to do this, thank you so much!
