Connected landscapes

Is it possible to connect landscapes, which have different rotation, withowt dragging them manually? I am making a walkable cylinder interior, and need to place multiple landscapes, each connected to previous at some angle (so that they sum as 360), but dragging a landscape is slow, and somewhat buggy (I can’t rotate landscape preview, but rotating and dragging already created landscape is sloooow. And dragging preview without rotating throws me at “paint landscape” tab before I confirm changes.
