Why would you want to do it inside the sequence? I have more and more favoured setting a new scheduler job for changes, so that the scope also re-aligns. This to minimize the risk of failures affecting the whole night. For instance, if something happens that makes the scope drift (clouds...), I don't want that effect to last for too long. So I prefer spending some time on re-aligning to safeguard and in the end, get more out of the nights. So I would set up each filter as a separate Scheduler sequence (or even split them into 30 subs per job). That said, the filter offset is really helpful.
