vb3 cron scheduled task every 30 min?

[Tekton]

I have some off-the-wall strange ideas, but is there a really simple way to do this?

Is the only way making one to run at 15 min and one to go at 30 min maybe? Well what about updating every 45 then? Is that impossible?

You would need to add it twice.
