Is it possible to disconnect a GUI program launched within vifm from vifm?

One can launch GUI programs, for example, gv or xpdf from vifm in background in vifm's command line: :!gv %f & However, if gv is launched by pressing Enter on a file like aPSfile.ps in vifm, it blocks the vifm. Is it possible to run it in the background as well when it is launched this way? The following setup in vifmrc does not work: FILETYPE=PS=ps,eps,epsi=gv & My current solution is to run vifm in GNU screen. gv launched by pressing Enter will run in a new screen instead of blocking vifm. However, I'd like to save that screen as well...
