You can only do it (best I can tell) by changing your Due Soon setting, but that changes everything, not just the perspective.
I’ve been testing out OF, considering moving to it. But the (apparent) lack of a way to do date relative filters in the custom perspective may be a deal breaker for me. Like I can’t make a custom perspective that shows everything from work due tomorrow.
I would think this must be on a development roadmap - or there is some serious technical issue preventing it - because this seems like a major, and obvious, omission from the perspective system.
