Adobe photoshop script

Hi Looking for a script to link multiple elements in multiple groups, in order to select in one go. For example say we have in layer 1(page 1), we have a group called languages (french/german/italy/spanish). In layer 2 (page 2), again we have a group called languages (french/german/italy/spanish) Same again in layer 3... The question 1. Is there anyway of linking all the french languages all together and all the german languages together, so when i click on one language in any layer, it is selected on all the layers. So if i click ok the german layer on all 3 layers it will select all the linked german elements on all the layers. 2. There is a script available to save all the layers once selected as seeperate PSD, i can then automate to create a multi pdf. Is there any way i can just choose the elements on layer 1, change the entire document and then it automatically creates a multi pdf of all the pages? Any questions, please ask.
