Reading OPC tags in Labview

I have created around 8398 tags under 247 different devices with address in NI OPC server 2012.I bound shared variables to the under OPC client which is creates as I/o server under my computer in project explorer.Right now I am planning to design HMI page where I have to show all those tag values with certain time stamp and data logging.
If I drag and drop shared variables individually it will consume lot of time for such huge no of tags.
 
So I want your help how can I retrieve tag variables according to meter by using any tag reading function or VIs in block diagram? 

 

 Here are some of the images of my work.
