{bb} Changing polling interval for one single https test

Guys, 

On a BB1.9c server on RH7.3 I'd like to modify the polling interval for 
one single https test.
I couldn't find how to do this in the docs, so in bb-hosts I've tried 
adding ";20" at the end of the URL (like this)

10.121.64.95   goofy  # noconn 
https://intraweb.righthere.net/secureCentre/default/login.secc;20

but that got seen as part of the URL itself (and not like "test it every 
20 seconds").

Any idea about how to achieve this within bb-hosts?

Cheers

Loris
