How to add new seniority rule to employee record

Summary:

Hello!

We have configured a new Seniority Rule and need to manually add it to 10 employees to test, however we're lost on how to add this new rule to each employee record.

Seniority Dates via employee record does not give the option to Add.

Please let me know where we're going wrong.
