Add an additional DGP(0) field like you describe. This could either be
a "compositional field" (but we would need to add the option to change
the FE and disable solving for it), or an independent variable (see
free surface for an example).
Track the information yourself in something like a map from
cell_iterator to double. For SolutionTransfer/Serialization you would
then need to add a signal to transfer your data.
Both things are not possible in a clean way at the moment, sadly. What
should happen with the values when a cell gets refined or coarsened?
If you need to control this, you need to go with option 2, otherwise
option 1 sounds easier.
