Parallel_add Megafunction help

Hello everyone, I'm an absolute beginner with the software so I'd really appreciate if anyone could help me with a very simple issue.

I'm building a FIR filter using Quartus Prime Lite Edition and I want to place a parallel_add block to add all my bus streams, problem is I can't alter the block to have it look like, for example, the second image I uploaded called p_add_5 in order to be able to add five buses. How do I do it?

Thanks in advance to anyone who took the time reading

    Double-click the block to open it's IP Parameter Editor. There you can set the number of input buses and their width.

      Like so? Because even when I alter the size and width, there's no actual change in the look of the block. I figured maybe due to the fact that I'm using the Lite Edition?

    Thanks Steven for your help on this. @Richardo, Steven is right. Generally it is recommended to instantiate the IP from the IP Catalog.
