Legato function on cubasis 3 ipad

Hello, cubase user for 34 years here …

I really would like a legato function for cubasis on iPad. When I use pro on my pc it’s a simple midi function / effect and all notes are legato.

I have looked at various auv3 plugins but can’t get one to give me a basic midi legato function

Is there even some way of doing this with a simple menu command?

Ideally I want to be able to select a phrase / a few notes and click a single button, or a few buttons and my notes in the phrase are now legato.

Any help would be appreciated
