Using relative dates to create audiences based on event data

Hi. The question here is how to use relative dates within event properties when creating an audience.
For example, I want to create an audience that automatically includes users who have performed a search for a hotel stay starting within the next 15 days.
However, when I try to create the audience based on the "arrival_date" property, I can only select a fixed date, not a relative date like "in the next 15 days."
Is there any way to solve this and be able to use relative dates?
