Can configure scanning of web pages one by one?

[tsukiazuma]

Hi,
I need check many URL of a website. But when changedetection run check about 10 url same time, it send a lot of requests to server web. This behavior increases server performance, is recognized by the firewall as DOS and blocks the IP.
Can I configure to run one by one?
It like check first URL -> done -> check second URL -> done -> .... Not run same time.
I try configure schedule, but it not feasible, because too many urls to configure

And one more, if can setup delay for fetch like check url -> done -> delay 5s -> check url -> done -> delay 5s ->....
