A soluation may be either checkboxes for relevant interferometers (as was done in the iLog), or list all the subsystems under the "Task" menu when the LHO "Section" is chosen.

This would be useful for classifying tasks such as:

- A subsystem purchases a tool, e.g. romer arm pr camera, for use throughout a site.

- Pcal calibrates a power meter that will be used for all interferometers.

- A seismic event happens that affects all interferometers.
