Mandate attaching Contract to Account when it gets automatically transitioned from a Lead

Hi,

I have setup a Blueprint that transitions a Lead across few states, and when it reaches 'Deal Won' the Lead gets automatically converted to an Account.

There is a Contract related list for Accounts, is there any way for when the Lead gets converted to an Account, the system prompts it to be mandatory to attach Contract to the account before proceeding?

Regards
