Hey folks, I'd like to be able to push a Flow Group's start date back arbitrarily to act as a hacky "Delay Run" method. I'm seeing that the mutation set_flow_group_schedule should do the trick, but its input parameters only give "timezone" as an option. This makes sense since you can pass in multiple clocks, but both the cron_clock_input and interval_clock_input lack start_date as well in the API. It looks like when you use the API to create/update a Flow Group's schedule, it just plops datetime.now() in as the start date, but I'd like to be able to define it per clock. Can somebody point me in the right direction on adding functionality like this to Apollo/Hasura?
