How do I extend surfaces in v2? Say I've created a cylinder, and all I want to do is extend ONE surface side. For this example it could be the back end of a pipe that needs to be longer, so the other end MUST stay where it is.

I've tried selecting the end cap and moving, select the edges and moving. Select the surfaces and scale 1D. Nothing.

My workaround is select the cap and extrude then boolean union. This still leaves a seam edge though which I don't like.

Suggestions?
