Let layer from Master slide stay in screen for longer

Hi guys, 

I am creating a game in Storyline 360. In this game have made a custom numeric score variable (Score_Overall) and a custom text level variable (Level), as the user in my module is going through different levels based on the score he or she has (e.g. <150 points = level Rookie; 150 <> 400 points = level Rising Start etc.). 

In the Master view, I have created a "Congratulations, you moved up one level" layer for each level with the following trigger:

Show Layer *Level*
When variable Level changes
If variable level = Level name

In other words, if a user passes 150 points, he/she will see a layer showing that he/she moved to the Rising Star level. 

This is working fine, but the problem is that when a user clicks an answer in a screen, it has the trigger "Add X points to Score_Overall and move to next slide". When this specific answer gives the user enough points to pass to another level, the "Congratulations" layer of the master slide is shown, but only really briefly since the user automatically moves to the next slide. 

Is there a way to make sure that this "Congratulations-layer" stays on the screen for longer? (I don't want to create a "next" button btw- I really want users to move to the next slide when they click their answer). 

Thanks a lot for your help!
