Priority dialog in ksysguard

The "prelink" program is launched daily by "cron". When "prelink" is running, I notice that my old computer works slower.

If I open "ksysguard", search for "prelink", right-click on "prelink" row, and select "Set priority...", I get a dialog window (see it in the attached image) that shows the following things:

    CPU Scheduler
        (*) Normal
        ( ) Batch
        ( ) Round robin
        ( ) FIFO
    
        Priority: Low (19)
    
    I/O Scheduler
        (*) Normal
        ( ) Idle
        ( ) Best effort
        ( ) Real time
    
        Priority: Low (7)

I think that "prelink" should run by default with a "Batch" value in the "CPU Scheduler" (instead of current "Normal" value), since the description of "Batch" value is:

    For CPU-intensive non-interactive processes.

And probably "prelink" should also run by default with an "Idle" value in the "I/O Scheduler" (instead of current "Normal" value), since the description of "Batch" value is:

    Process can only use the hard disk when no other process has
    used it very recently.

I think that, by changing both default values, "prelink" will not affect other programs running on the computer. Would it be easy to change?

Thank you
