Spice model import to ADS schematic

Hi,
Is there quick method to import spice model into ADS schematic?

I know how to do manually for transistor models by editing the 30 to 40 parameters. It becomes too complex if the spice model contains sub circuits etc.

Please help

If you know how to edit netlist file, you can do it more quickly. But I don't know how to do that. There is someone in this forum who can restore ADS file from netlist file.
