We certainly have an existing mechanism which may be set in .sbuildrc
or sbuild.conf:
$sbuild_mode = "buildd|user"
This does not currently encompass Distribution handling, but could
be made to do so.

In the last few releases, I've refactored local building to allow
this. sbuild itself only operates on source packages; previously
local building required generating the source package and then
operating on the .dsc. We now (internally) only deal with .dscs.
Local building is done at the top level prior to creating and running
a build job. The implication of this change is that it's now possible
to run dpkg-parsechangelog and change the distribution default when
building locally. This is the case right now.
This still doesn't solve the problem of building a local .dsc,
which would require an unpack of the source package to determine
the distribution, but does solve it for unpacked sources.
Adding support for using a .changes file in place of a .dsc is
still on my TODO, list. Once a .changes is accepted, we could
only permit setting the distribution in buildd mode.
