No value option for single value in multi-value stats panel

I have a panel that displays the process timestamp of multiple files.
The data comes from Zabbix and is updated only once a day during the night. So, there’s only 1 value every 24h.

During the day Grafana’s panel displays the correct data, but during the night, the data is mostly absent since the values take a while to update.
When there’s no value at all, the panel displays a “File delayed” message.

I needed it to display the delay message for each individual file row.

Any idea how to do so?
Thank you.
