Sliding door blueprint +placing the door

Hey, I am new here and I have a question. I am working on a sliding door blueprint and I got that working fine but setting the location to a variable manualy is a lot of work. Is there a way to make a blueprint place a door and triggerbox while adding it to this blueprint?

Try having your time line consist of a single float from 0 to 1. Then have your vector variable marked as public and with the 3D widget. When you place your door blueprint, you will see a diamond ish widget. When you drag that around your scene it will change your variable to be that spot.

Multiply the float value from the timeline by the vector variable. You can then add that to your initial location.
