Not possible right now as we only allow one public topic timer (publish, closing, opening) per topic. As a workaround now, you could set a publish topic timer and add a reminder for yourself to close the topic.
Could you build on your use case a little as to why you have a need for multiple topic timers? Multiple topic timers is not impossible but tricky to deal with as we now have to make sure that there isn’t any overlap with the time range.
