Port isService property (SysML)

[Guillaume]

Hi,

In my SysML BDD, I define the block's port by setting a block as the port's type. When the port has flow properties (according to the block definition), it can be useful to revert it via the Conjugated property set to true (open the port properties > Advanced tab).
I noticed there is a isService property that can be set to true/false. I don't see any rendering difference changing the value. Is that supposed to be doing anything?
Currently when a port provides features, I manually add a Provided Interface so we know it provides services (since SysML 1.3)
