[Q] remove selected text from calender title? topic

Hello.
Is it possible to remove selected text from the calendar title.
Example, say the word "SPRING" appears on many of my titles but I want that word removed if so, is that possible?
And what if I want to remove one word and then also switch another one?
Example, change. .. SPRING: GIANTS AT PADRES
into... GIANTS @ PADRES

So "Spring:" is removed and "AT" is switched to "@"

I want to do even more than this, but I'm hoping I'd some one could show me how to do this, If it's even possible, then I could expand it from there.

Thanks.
