Zoho Flow - need to format the System Variable -> Current Date

Hi, 
I am unable to format the System Variable --> Current Date in Zoho Flow.
Please let me know how can I format that date. 
Currently the System Variable --> Current Date appears as e.g. : 2020-12-31 
I need to show that date (in subject line of emails, Desk tickets etc.) as: 12/31/2021. 
Thank you!
