Yes it is possible.
Tvheadend has three different recording modes. The first, simply called "recordings", records a single item selected from the EPG, using the start/stop times from the EPG. The second, called "timers" will record a given channel between given start/stop times. The third, "autorecs", will record a series of items as defined by the EPG.
So for your use case "timers" (Digital Video Recorder -> Timers) will do what you want.
