User-Defined Message Sequence Number
In our older version sequence diagram, messages are auto-numbered and there is no way to customize them. Now you can select to manually specify message sequence number when auto-numbering cannot fit your usage.

Setting Message Sequence Number Handling Method
Message sequence number handling method can be either one of the following:
Automatic - Sequence numbers of messages will be updated automatically after you moved the messages, and you cannot specify custom sequence number to messages.
Manual - Sequence numbers of messages will not be updated even after you moved the messages, and you can specify custom sequence number to messages.
For sequence diagram, right-click on the diagram and select
Sequence Number from the popup menu, then select either
Automatic or
Manual.
For communication diagram, since there is no automatic message sequence number handling, so it is always manual.

After you have set its message sequence number handling to manual, right-click on the diagram and select

For example, this picture shows the messages before reset sequence number.
If clicked
Reset Sequence Number from 1, the first message in the table will be numbered 1, the second numbered 2, and so on.
If clicked
