Artist states and include files

I wish to use include files with Analog Artist to access features of
the simulator (Eldo) not available through the GUI. I also prefer
typing control files to all the clicking!
Without a path such an include file is stored alongside the simulation
data which isn't great as the simulation data is transitory and isn't
generally considered part of the design.
I would prefer for the include file to be stored with the state data
as this seems logical - this is where I stumble. Manually entering a
path is a pain - files will end up all over the place.

Is there a machanism to support this? The only state related functions
I can find only launch the load/save windows.

Is there a function that returns the name of the most recently loaded
state and its location? Is it possible to trigger a function on state
save/load to bring in additonal data?
