CI calculation with orbitals from external source



is it possible to use detci as a CI solver for a reference wavefunction from a third software?
I was hoping for a way to directly load all the intergrals from an existing FCIDUMP file and pass them detci.

Alternatively loading the molecular orbital coefficients and basis set (from a molden file) could work, i.e. setting up a SCF wavefunction object, and then passing it as reference function to detci. But this seams more elaborate.
