I am attempting to customize some symbols, but I am having issues with the attributes after the symbol is modified. For example, I took a generic compression driver, unlocked the symbol, moved the text blocks around, and edited their attributes, then saved the symbol in my libraries. This works fine, but as soon as I modify the shape or add extra lines and "group" the new shapes it loses all the attributes and I cannot "click assign" the attributes. Also, what if I wanted to add a text box with a different attribute to an existing product? This doesn't seem possible as the attributes for the symbol do not show up when adding attributes to the text box. So if a speaker has two text fields, but I need three, I can't do it. Am I missing something in the process?

Thanks!
