How can I filter the work breakdown structure (WBS) 1 decimal point?

I'm trying to figure out how to share the view of the WBS by only 1 decimal. (1.1, 1.2, ...3.3, 3.4, etc.) I do not want it to exceed more than 1 decimal (1.1.2, 1.1.3, ...3.3.1, etc.) - Is there a way to filter the column by this way?
