Multiplicity display in activity diagrams

I have a pin in an activity diagram. The pin is associated with a parameter that has a specified multiplicity and a specified effect. How can I get this information to appear textually next to the pin on the diagram itself?

Hello DanielG,

I’m sorry that currently we do not support showing the multiplicity value of the parameter in the pin. We will consider to support this in our future release.

Best regards,
Rain Wong
