Multi select option for variables

It would be nice if we could shift-select multiple variables; bools floats, integers etc, and then change the category all at once rather than one at a time. It would just really help to organize projects better. I know everyone that drops 40-50 variables into a project has to go through, and click each one individually to change category in order to not make a total cluster out of their project. Unless theres a way that I am not seeing to do this. Thanks
