How do I associate tolerances with an extrusion?

Is there a way to create an extrusion, and associate a tolerance with it? I can create a line in a sketch, and dimension the line, and also add the tolerance to the line dimension callout. I can't seem to find a similar option for doing this with an extrusion, or anything in the features tab of Solidworks. Is there a non-complicated way to do this? I have seen online a few references to linking these dimensions to a table. I don't really want to do that, I just want to add tolerances to my part as I make them, rather than trying to remember what those tolerances are when I get around to making a blueprint for them.

Thanks,
