URGENT: Sandbox limitation for Azure Challenge

Dear Colleagues, 

I'm working on Azure Cloud Challenge and just 4 modules left to complete.

I'm getting the message

"This module requires a sandbox to complete. You have used all 10 sandboxes for today. More sandboxes will be available tomorrow."

Problem is the challenge ends today 😞 - 2/13/2021

Is there any way to use my private paid Azure subscription instead of Concierge one or to request 

additional sandboxes just for today so that I can complete this Microsoft Learn Challenge ?

Any advise please 

thanks

Yuriy
