Different Intervals for Different TCP Tests

We would like to configure hobbit such that we perform ping tests at 1 minute intervals, and we test the other TCP-based services (ssh, ftp, imap, ...) at 5 minute intervals.

Is this possible and how would I do it (and, if it is possible, is it advisable or should it be avoided)?

Thanks.
