Inquiry on how to put an existing DIV in Layout

Is there a way to insert an existing DIV into the layout?

In version 5.X I used appendObject . It seems impossible with AttachHTML because the HTML content is complex.

For Example) 5.X Version

lay_Main.cells("a").appendObject("div_Left");
lay_Main.cells("b").appendObject("div_Right");

You may init a layout cell with some empty container and place your div in that container.
