Elements - Pensionable Hours

SUGGESTED

When setting up an element, there is a tick box for Pensionable Hours. Does this just relate to what will appear on a report as a Pensionable Hour?  For example we have enhancements for a Saturday. As this is not a whole unit, I do not want to include this when looking at how many hours are pensionable. Would I therefore untick this box. I still need the enhancement to attract Pension contributions but when I run a report not be included . Hope this makes sense.
