I am using Altium Designer 16.1 for a project which has about 6 thousands of components, so I have many Net Lables(at first I designed a small circuit in a schematic page then by copy and paste I create the whole project).
I used Annotate Schematics option in the "Tools" menu to rename the components, Is there any option to rename the Net Lables automatically like annotate option?

The best way to do this in Altium is to use Net Ties. These will join two separate nets. See: https://www.smtnet.com/library/files/upload/NetTies-and-How-to-Use-Them.pdf
I will also occasionally use zero-ohm resistors to accomplish the same goal if there is a chance that I may need to break the connection to help troubleshoot an issue.
When you design your schematic component, assign Designators to the pins, e.g. A + B or 1 + 2, .... In your PCB Library item (the one that is linked to your schematic symbol) use the Place -> Pad, select "Multi-Layer" as Layer, enter a hole size (.7mm) and a pad size (e.g 1.5x1.5mm) and you're done, name the two pads A + B (same name as in the schematic).
Now when you transfer your schematic design to your PCB, Altium will assign the appropriate nets to your pads.

EEK.. unless you can edit that in a text file or something you may be out of luck..
For future reference, the better method for something like this is to make your design hierarchical.
Create a single page with the common circuit with an associated symbol, then instantiate N of those symbols on an interconnecting schematic page.
The software should handle the rest.
