If Employment Model of an existing LE is updated, can we add contract to an existing employees?

Summary:

We have an LE where employees are already hired and it was a non-contract employment model LE. A new requirement came to add contract details to these employees.

So, we updated the employment model at LE level from non-contract to contract enabled LE. From Employment Contracts page there is no option to add contract details.

Is it possible to load contract details using HDL to these existing employees?
