Ice cream contract to JK lol

[Jeannoune]

Hello
I think I've been foolish and I progressed in the ice creams before doing the contract. Now I'm at the forlast icecream and I saw I'm supposed to reach JK lol.
Let's say... It's so so hard and difficult and it takes ages.
So my question is the following: any chance I can accept again a previous icecream so that it's way more easier ?
I'm affraid to deliver this icecream and never be able to validate the last contract :'(

Thank you for your help

the wiki says that after finishing the ice cream challenges, you get a gold ice cream that doesn't reduce damage

Damn I feel so stupid ahahaha
I spent the last days trying this so hard. Well I'm not so far anymore so I'm going to stick to finish it.
If anyone is struggling like me, I can tell you to upgrade the Enigmatic Boosters to + 10M Value minimum + having the secrets found.
I forgot about it and this upgrade just changed completely the game. I'm killing 100M in a minute (versus 1M a minute before) and should be done with this challenge very soon ^^'
