I have a workflow rules in Lead module that will be executed when a lead is created or edited like this

if 'Whatsapp ID' field contains 'BR-' then the 'Marketer' field should be updated to 'Internal',

I use Zoho CRM Blueprint to qualify a lead to be a deal. I expect If I change the value of a field in Blueprint, then the workflow rules in lead module above will be executed first to my lead record before I eventually create a deal record.

but actually the field  'Marketer' is not updated, thats why I have an empty value in 'Marketer' field in deal module because the lead conversion mapping doesnt work as I expect

so How to execute Workflow rules or function in lead module first  when a lead is being qualified.

or maybe is there any better way to solve this issue?
