Need a Custom Calendar Event for 2nd and 4th Thursdays in month

I need to set a calendar event reminder for the 2nd and 4th Thursday every month. The only recurring calendar choices are every week, every 2 weeks, etc. Every 2 week and 4 week recurring event on Thursday does not align with every 2nd and 4th Thursday of the month.

Please develop a recurring event selection in the Calendar that accommodates for the selected DAY as the first, second, third, fourth, fifth week of the month.

Thank you.
