How to remove applications after the event date is over?

In my “JOBS” tab, it shows all the jobs I have applied till now. The event dates are over but still they are not removed from my applications. Will I be able to apply to the company next time when it posts a job? If not, then how to to remove expired job applications? Also, once applied, the job notification gets removed from the “ALL JOBS” category under “JOBS” tab. Will I be able to apply for future jobs at the companies?
