time event triggers in SysML State Machine Diagram

[bechbp]

Hello,

I am working on a State Machine Diagram (stm) using the SysML nomenclature. The stm displays triggers as text on transition lines. I have a time event trigger (Name: Timer, Specification: 2 min). 

Per SysML, this time event trigger should be displayed as "after (2 min)" on the transition line.

But in EA, I can't get the time event trigger to appear as such. Instead EA only shows the trigger name "Timer" on the transition line, rather than it's specification.

How can I get EA to display the timer trigger correctly per the SysML nomenclature?

thanks
