Clock Network Selection Example for Cyclone V

Can any one share method or example on how to select specific clock network region on Altera SoC. Any board will be fine but it will be best if you can please show me example related to cyclone V.
For now, whenever I assign clock to my design, I assign pin K14 to my Cyclone V SoC Board (5csxfc6d6f31c8) and I don’t even know if it is a global clock or regional clock.
I just wana know how can I select particular clock region because in altera manual it is just written that there are global and regional clock networks but there is no method on how to select them?

Here is the schematic just in case if you need…
