For example, create a new variable called 'NewFeedSeconds' and set it's value to 300 (5 minutes).
Then add 2 measures, a time measure and a calc measure. The calc measure uses modulo math to reset the formula value to zero based on the number of seconds in the Time measure defined by 'NewFeedSeconds'. The If Condition will test if the value is zero and if true, will increase the currentfeed value in a loop from 1 to 6 and command the reader script to show the next feed.

Note that the above measure changes to the next section after an interval equal with the UpdateDivider value (in this case 5 x 60 = 300 seconds).

I couldn't get the first solution to work, but your solution worked. Thank you very much. I knew it was something with the Loop measure but I couldn't wrap my head around it. Seeing your solution helps me understand it better.

As usually, there are more solutions, mine is just one of them. But I'm glad if it did help you to understand things better.
