How to Manage External Netlist Files

I am able to simulate with external Spice netlist with similar approach in "How to Simulate a Subcircuit (Netlist) With Spectre in ADE"  what I did is to set the model to the full path name of the simulated netlist file in the newly created symbol view and this work fine.I can also create a separate text or spice view like "myspice", "mydspf" to hold the netlist files and let the design manager to checkin the netlist file. This requires me to create one symbol view like "mysymbolview" and another spice view like "myspiceview." I am trying to combine these two views into a single one. I now have two new questions:

(1) Can I set the value of the component parameter "model" to a skill function that returns the concatenation of the absolute full path name of this symbol view and a file name like this "fullpathto/mylibpath/mycell/mysymbolview/spice.spi?" The benefit of this is that we do not need to update the hard coded full path name once this cell is copied to another library.

(2) Can I let the third party library design manager to check in "mylibpath/mycell/mysymbolview/spice.spi" to mysymbolview.I tried putting a data.reg in my home directory:

+DataFormat schematicSymbol {
    Co_Managed = master.tag thumbnail_128x128.png symbol.oa spice.spi;
}

and the design manager does not seem to pay attention to this registration file after I restarted Virtuoso. I am new to how the data manager works by the way. If you can confirm that (2) can only be done by the third party design manager, I can ask our tool support engineer to relay this question to the library design manager vendor.

Any help to solve the above two questions is greatly appreciated.
