Making the lenght composition match one of the clips

[brunosdk]

Hi. I am really new to AE. I am manually changing the lenght of the composition, but I would like to know if there is a way to match the lenght to the clip I am importing. I am not trying to make a composition from a clip, I know that will give me the desired result. I am already having compositions and I am importing in each of them a new clip. I am manually changing the composition lenght to the clip by checking the clip lenght, but Its a bit tedious to do it for each of them. Is there any shortcut or workaround to pick a clip within my composition and make that composition magically extend till the end of the clip?

Regards

Set the work area, then use Composition --> Trim to Work Area.

move the timeline to the end of the clip then press ( N ) to set the work area to the end, then right click on the workarea and select Trim comp to work area.
