Pick object with property

I have set up a ladder climbing system for the platform behaviour, which basically switches to 2-directional (up/down) movement whenever you trigger ladder climbing. Which objects you can climb are determined by a custom "Climbable" attribute.

I want to snap the player object to the center of the ladder, but I cannot seem to find any way to pick the ladder object I'm interacting with so that I can retrieve its X value. Is there no way to do this in Construct?

Check if the player and the ladder are overlapping eachother, that will pick the right instance of the ladder.

It seems like there is no way to pick an object based on its attributes rather than object type, but I guess it's not a problem -- I can just use a specific object that can be climbed and make it invisible, while having a tiled background object on top for graphics.
