For link monsters that requires 2 or more monsters, how can i make it so i just have to use 2 monsters and not every monster on the field

Basically, when i try to summon my knightmare unicorn and i just want to use 2 of my montsers when i try to only use 2 montsers it only gives me an option to cancel or to just keep using montsers
Is there anyway i can just use 2 monster?

Knightmare unicorn is a Link 3 monster. That means you need 3 monsters with 2+ treated as different names. You can use 1 Link 2 monster (treated as 2 monsters) + monster as well.

ohhh ok im so dumb ty
