Using a model file as one of the templates

[sasson iris <sassonir AT cs.bgu.ac.il>]

Hi,

I want to use models as well as templates to build a new model using 
modeller. That is, I have a few models that were not created by using an 
alignment and some alignments.
How can i make modeller use all of which to build a new model?

Thanks,
Iris.
