In my bachelor thesis I have a few references that consist of several bibliography entries that are grouped via
biber as backend). Now I wonder if it is possible to add some text within these grouped entries, for example to indicate an erratum paper by adding something like "(E)" after the entry:
 J. P. Perdew, K. Burke, M. Ernzerhof, Phys. Rev. Lett. 1996, 77, 3865; J. P. Perdew, K. Burke, M. Ernzerhof, Phys. Rev. Lett. 1997, 78, 1396 (E).
Another example would be the creation of a reference with grouped entries that should look like this:
 E. H. Lieb, „Density Functionals for Coulomb Systems“ in Physics as Natural Philosophy: Essays in Honor of Laszlo Tisza on His 75th Birthday (Eds.: A. Shimony, H. Feshbach), MIT Press, Cambridge, MA, 1982, pp. 111–149; a revised version appeared in E. H. Lieb, Int. J. Quantum Chem. 1983, 24, 243.
In the last example the phrase "a revised version appeared in" is the part that should be added to
biblatex's standard output.
My question is: Can this be achieved with
biblatex (or another package) or do I have to make these changes manually in the
