SnapVault Qaurterly and Annual Schedules

Hi,

I'm not able to create schedules for quarterly and annual SnapVaults either natively using the CLI or via PM (PM creates monthly scheules but nothing beyond that), is there a workaround or do I have to use a bespoke script?

If the latter can anyone share a script which does what I'm asking in ONTAP 8.2.x 7-mode

Thanks,
