Unfortunately it is not possible. You may place a header on the top of a content, or a footer below a content.
Starting with v396 it is possible to achieve the needed layout a tricky way. The most recent PD4ML version support a page overlay.
You may create a main PDF with some space reserved left side (using a left margin/inset etc). The second document should render only content, goes to the left side. After the docs are ready, you may combine the docs into a resulting one (by a placing of the second doc content over the first doc’s content).
