The Dynamic Component Attribute dialog is probably designed for single selection. Depending on where exactly the attributes are stored (component attributes, sub-entities etc.) you may have success with the Attribute Inspector extension. Like SketchUp's Entity Inspector, it works with multiple selection. First select one component and find the attribute to change. Then select all and set the same attribute.

I have posted a "corrected" version of Align & Distribute plugin on my blog. I had created a second version when some one requested the ability to just distribute, or not aligned, N/A. So when I updated the posting, I unfortunately got the plugin and the support files mis-matched. That is why the radio buttons didn't work. When you click on the plugin link, you will get a list of the contents of the zip file. This is not my choice but just the way Google Drive handles things. Click File and select Download. When extracting the contents of the Zip file, it is only important that the AnD_Support_Files folder be a sub-folder of the folder containing the plugin whether that is the SketchUp Plugins folder or some other. Normally you will want to pre-select the Components and/or Groups that you want to align and/or distribute but, if you don't, you can select the individually by left clicking on them and pressing the Shift key when done. To change the selection, press Shift and repeat the selection process.
