If you have multiple timestamps of one project you’d like to merge to one single timestamp, you can do so. Just mark the timestamps with the mouse, right-click on the timestamp and choose “Merge”.
Even if there are gaps between the timestamps you can merge them. You then have to decide what to do with the gaps. There’s two options. You can either just add the gaps to your timestamp, so the ending timestamp will stay the same, but the duration will extend, or you can subtract the gaps from the total time, so your ending timestamp will move to an earlier ending, but the duration will stay the same.
