Programmatically create PI trends

Hello there, I want to create monitoring trend for about 400 PID controllers. Trend for each PID loop will have PV, SP and OP. I am thinking to have 9 processbook trends on one display so that every morning I can quickly go through these display to monitor PID performance. 

I am wondering, can I create these trends programmatically (VBA code???), if I have all the tag names in excel?

If possible, can you please provide me direction?

Thanks
