How can i stretch part of a geometry with a modifier? is there any option to stretch just part of a geometry?
Like my image? i only need to stretch a little part of the model, i could do it on edit mode but it could be difficult since i got already a lot of polygons, is there any other way?

Thank you in regard :)



Edit: i already tried with the edit mode, but it doesn't work properly since it doesnt fit the figure like i want.
Already found a way to do this, i just entered in edit mode and then used the proportional editing option, and also the snap option, it worked! but i just selected the faces i wanted to stretch :)
