Allow cycle offsets for things like `cylc set ... -pre=...`?

I was wondering if it would be possible, and reasonable to allow users to do commands like cylc set –pre=-PT6H/task:succeeded ... - use of offsets rather than having to pre-calculate the appropriate cycle? This would add more power to things like cylc set workflow //20250917T0000Z/task //20250916T0000Z/task –-pre=-PT6H/other_task:succeeded- so one command can hit multiple cycles at once.

It should be relatively simple to implement, if you wouldn’t mind opening a feature request issue on cylc-flow on GitHub. Though I can’t promise we would get round to it very soon

Might be worth linking Relative Inter Cycle Dependencies · Issue #2452 · cylc/cylc-flow · GitHub into that issue.

Should close this old issue as superseded insert by relative cycle syntax · Issue #2750 · cylc/cylc-flow · GitHub by this more general one.
