Macro for host PSK, or another way to define a PSK for reuse?

[mko7]

Hi,

We want to enable agent encryption on a lot of hosts using a standard PSK and store the PSK once rather than having to enter/update it on every host. Trying to use a global macro in the host PSK field gives this error:

Incorrect value for field "tls_psk": an even number of hexadecimal characters is expected.

Is there another way to define a PSK that can be reused in the PSK field for many hosts?

Thanks in advance (and for Zabbix!).
