Even date schedule for hose timer

I’m trying to make a schedule for my hose timer that will run on even dates. It seems like this is not exactly an option for the hose timer scheduling. Instead, I set up a schedule with intervals of every other day. But no matter what I have tried (different settings, like a start date on an even date), it always begins on an odd date. Is there any way to change this? I chatted with support but they said there is currently no way to do what I want without a lot of manual scheduling.

The workaround I’m thinking will require having to set up a new schedule for each week, so any insight would be appreciated!
