How to customize quiz score slide in Rise

In response to Savii's question

'Hi, Want to customize the quiz score slide in Rise, please suggest.Regards,Savvi'

I notice that in lables,  'Quiz Result'  can be customized to another word BUT it only gives me so many letters. I want to add a direction to the words Quiz Result what to do next and will only let me add a space and the word 'if'. Looks like it only allows 14 characters. Is there a way around this? So I would like it to say Quiz Results - if 79% or under please try again
