Automation to Create Item on Last Business Day

My team has started to offer documents or wire transfers to clients on a recurring basis, and some are on the last business day of each month. Currently, we have an automation to create an item on the 25th of every month, but it would be preferable to have it generate on the 29th, 30th, or 31st depending on which was the last business day. We’d like to avoid sending it too early or missing the last business day and sending too late.

Thanks for your time.
