I am unable to form a chain of successive events when one of the events is a subevent of another event.
Example:

1. A manuscript was bought in Istanbul: https://mamems.openatlas.eu/entity/6462
2. The buyer took the manuscript with him to Vienna on his return trip: https://mamems.openatlas.eu/entity/1291
3. A scholar later wrote notes on the manuscript in Augsburg: https://mamems.openatlas.eu/entity/7294

All three events are linked via tabs to the artifact entry for the manuscript (https://mamems.openatlas.eu/entity/4923), but the acquisition (event 1 above) is a subevent of the person's stay in Istanbul (https://mamems.openatlas.eu/entity/6462), so I cannot indicate the acquisition as the preceding event of the transfer (event 2 above) - the preceding event of the return trip is the traveler's stay in Istanbul. Is it possible to show the three events that form the history of the manuscript as successive events? This would also be important for the presentation website, to highlight the "biography" of the manuscript.
