Calculating a future date using an Event Trigger Date

Hi everyone

Still learning my ropes around Klaviyo and the dynamic variables. I found an article that allows you to calculate a future date using the “today” syntax, however does anyone know if it’s possible to calculate a future date using an event trigger property? I assumed that by adding the ‘days_later:XX’ filter, this would have made this possible, but it’s throwing an error. 

Variable Code: {{ event.Invoice_Date|days_later:90|format_date_string|date:'d F o'|default:'' }}

Scenario: Wanted to communicate to customers payment due dates based on their order invoice date. 

Any suggestions and guidance would be highly appreciated!
