Is it possible to set a value on a field based on the user creating the Lead

Hi,

Is it possible (by layout rules or functions) to set a value on a field based on the user creating the Lead, while we are creating the Lead.

Example
In Leads, I have a custom select field "Division", with the options "Digital, Engineering".
This field is required, and I want it's default value to be set based on the User creating the Lead record.

The user also have the field "Division", so that a check could be done with user.division == "Digital", and set the lead.division value based on that.

Thanks in Advance.
