When I did this for a few teams, I bought really large magnetic white boards (the high quality kind that don't suffer from marker burn-in) I believe these were 12ft x 5ft (3.5m x 1.5m). You can then also purchase either electrical tape (comes in colors) or "chart tape" (which can create much thinner lines) Then you can lay out your board as you want. Neither tape leaves a residue, so easy with 10 min of work to change the layout. The magnetic nature of the board is great in general as well.
Note: We also had "movable" whiteboards that could be unhung, moved to a different conference room then rehung. For those, we created things like a "risk board" where we drew in permanent marker on those boards for the background then in dry-erase for the variable data this worked well and the Sharpie will actually come off (draw over with dry erase, then wipe off) but since these layouts didn't change much, we were okay with the permanent nature of the board.
Note: This is an "expensive" option. I think the magnetic whiteboards were $850 each (we bought one for each team) and the movable were about the same, but much smaller (figure 3-4 for each team)
Note2: This lasted about 6 months where the managers were "doing everything by hand" to become familiar with the process. After a few months they knew the process well enough to know what to look for in a tool. Then, we went SW and never looked back.
