Does OP support work contours?

I’d like to be able to back load some tasks, rather than have the amount of work be flat over their duration. In some cases, I’d also like to front load tasks. Is this possible in OP? If it is, I haven’t found a way.

I guess in general I’m asking whether it’s possible to set work contours for tasks: front loading, back loading, double peak, early peak, late peak, bell, and turtle.

Well, i’m going to interpret the lack of a reply as a “Nunh-unh”.
