Zabbix 4.2 monitor backup

Hi, i'm doing backups on from old servers with rsync and i would like if you could to add up as a feature request a monitoring item for symlinks , if it's possible because i haven't found a way to monitor the backups by symlink, tried with vfs.file.time on the folder that holds the backups, but if a backup fails and a inprogress folder remains, it won't fire what happend, but by monitoring the symlink i'll know when it changes. If there is a route i can use to attain this please let me know if not , could you implement it ? Thanks. I've also posted on forum, but no luck so far.
