insert effects to a part of a track

I am new in working with Cubase, using LE AI Elements 9.
How it works to insert effects in only a selected part of a track. I only got it to insert effects for the whole track.

Use a send and automate or automate insert bypass or cut selection to new track… just some quick thoughts!

Thank you, Split, tomorrow I`ll work it out, than you here from me, how it worked…
