There is no function for it but perhaps a little workaround.
Go into the patch and switch "columns" to full, select "Fixture Types" and then the FT you want to see the parameter.
Now you can move all fixtures of this FT into a free universe"s" e.g. 100.
Go to DMX Universes in the patch and have a look at the coarse parameters of universe 100.
This are the real parameter without the virtual.
If you leave the patch "Discard and Exit"
Maybe it helps!?
