Feature request: Show simultaneous tasks

[vkozloff]

Some tasks may be done simultaneously: while the experimenter does one task, another experimenter does another task

@vkozloff Do you mean two experimenters collect data in parallelly for the same experiment for the same subject? Could you please give an use case?

[vkozloff]

Sure. For example, Experimenters A and B prepare an EEG cap. This may take 15 minutes and some data would need to be collected about the impedance of the channels, etc, during setup. During the setup, Experimenter B administers a five-minute survey for the participant to complete while they wait.

It would be great to show that the total time is not 20 minutes, but 15, since these tasks occur simultaneously.
