Ruled-base filter of selected elements by properties, families and types (not only by category).
Some times I want to select varius families of one category, and the only options I have do a select all in a fist family, then select the others manually or, do a filter by category and then unselect unwanted objects. In other occations I want to select, for example, all walls withing a specifict length or height and thats is imposible to do practically, so you have to make a table with filters to do that selections.
