Offset Lines in Model Tree - Can They be Removed?

[MechEngSS]

I have an assembly, which is made up of a bunch of sub-assemblies, so we have created a lot of different exploded views for use in drawings, manuals, etc. We now have dozens of Offset Lines listed in the model tree. Is there any way to filter offset lines out of the model tree? I know that I can suppress them and then filter out suppressed objects, but I'd rather not do that, as some parts may also be suppressed at times. Thanks in advance.
