pspice bsim

As I know , Orcad can only accept Level 3 spice model for CMOS circuit simulation . Can Orcad 9 accept Bsim level 49 or higher model for simulating CMOS circuit ?
The simulator has:
The simulator provides six MOSFET device models, which differ in the formulation of the
I-V characteristic. The LEVEL parameter selects among different models as shown below. For
more information, see References.
LEVEL=1 Shichman-Hodges model (see reference [1])
LEVEL=2 geometry-based, analytic model (see reference [2])
LEVEL=3 semi-empirical, short-channel model (see reference [2])
LEVEL=4 BSIM model (see reference [3])
LEVEL=5 EKV model version 2.6 (see reference [10])
LEVEL=6 BSIM3 model version 2.0 (see reference [7])
LEVEL=7 BSIM3 model version 3.1 (see reference [8])
Level 7 is the level 49 of hspice (similar).
Levels 49 and 53 BSIM3v3 MOS Models
The BSIM3v3 MOS model from UC Berkeley is available as Avant! Level 49
and Level 53 models. Level 49 is an Hspice-enhanced version of BSIM3v3
while Level 53 maintains full compliance with the Berkeley release. This
compliance includes numerically identical model equations, identical parameter
default values, and identical parameter range limits.
