Hi,

That does not exist (yet).

AddAndActivate does three things:

  1) make a partial profile complete (e.g. with information from the
AP/specific-object).
  2) add that profile.
  3) activate that profile.

There is API for doing steps 2) and 3). But there is no API for step 1)
alone.

That would be a useful feature.
