How to move your transactions to an event?

When you add a transaction, the last step consists in classifying it into an event, this step being mandatory: every transaction is linked to only one event. 
If you want to change the event to which one or several transactions are linked, you need to click on Timeline in the left menu: 

1️⃣ On the event to which you want to link the transaction(s), click the 3 dots "..." at the end of the line, then click on Edit transactions.

2️⃣ Select the transaction you want to link to that event. 

The transaction is automatically linked to the event and deleted from the previous event it was linked to.
