Delay on custom sql alert

hello,

is there a way to delay alerting on alerts configured with “custom sql” (“Override SQL” switch to on on the advanced tab)?

it looks like the custom sql alerts get sent immedialty to the transport and not after the configured ‘delay’.

is it posible to enable the delay for custom sql?

as a workaround, may I use custom SQL to set some field I may use in a ‘standard’ alert with delay?
