Fast Formula Stop_Entry defaults to Pay_period_end_date can this be changed

Question:

Can you specify the date that you want the element to be end-dated when using stop_entry?

E.g. I have an element that i want to be end-dated based upon a person's age. Using the stop_entry, i can have the element end-dated to the pay period end-date, is it possible to make it automatically end-date at a specific date instead?

Thanks,
