When creating an "send email" action in workflow manager you can send
to "Logical User".

Can we use Logical user in other actions.

What I want to do :

When a lead gets converted to a contact, account, opportunity, I want
to assign all that to the user who made the conversion.

Do I have to use the SDK to do that kind of stuff ?

Is the Workflow manager working only with static values ?

TIA
