Add product attributes in Zencart

I need to have an easier way to add product attributes to my site other than using the ATTRIBUTES CONTROLLER (it is too time consuming) in zencart. Is there a way to create or install a check box or a drop down menu so I can select the attributes? Currently, I am having to enter each attribute one at a time...Many of my products have several sizes and/or colors that need to be added as drop down boxes on the website and I need a way to add these faster. example: [login to view URL]
