Currently OpsManager's maximum retention period for backups is 84 months (7 years). We have the requirement to keep 10 years of backups, hence adding some values (96, 108, 120, 132, 144) in the "Store monthly snapshots for... months" in the backup schedule would be helpful. Another option might be to allow custom values (I guess this is the purpose of https://feedback.mongodb.com/forums/924355-ops-tools/suggestions/39441955-make-snapshot-retention-policy-more-customisable)
