Schedule backup for 1st Sunday of the month

[McHenry]

I wish to perform a full backup to WASABI monthly on a Sunday when the bandwidth impact will be least noticed.

I cannot see any way to schedule a backup for the 1st Sunday of the month in XOA/XO

The cron command is:

00 09 * * 7 [ $(date +\%d) -le 07 ] && /run/your/script

Can I edit the cron file directly in XOA/XO?
