One robot - several processes - two triggers?

Hi everyone!

I have a question in regards to organizing my processes and triggers.

I have one robot that monitors three queues. The trigger is set automatically. The robot works great.

Now, I want to add another process that monitors another queue, but this will run ONLY in a specified time let say 00:00 till 06:00 AM, and then after its done it will continue working on the other three queues.

Let me give you an example:

06:01 - 23:59
Regular Queues

The Robot monitors three queues. It is set to automatically trigger and process anything New that comes in on the three queues.

00:00 - 06:00
Midnight Queue
The Robot stops monitoring the three queues. Moves to another queue where it does the same thing - automatically processing any New queue items until 6AM. Then stops that, and moves to the regular queues.

I have read some tips here but I cannot fully grasp how this will be organized with one robot.

I think it is pretty straight forward but I need some advice step-by-step how to put it in place
