Hello, Is it possible picking SKS phase in SSS?

for S phase picking I used following command.

SAC> sac
SAC>r *SAC
SAC>sss
SAC>traveltime phase S picks 0 verbose
SAC>qs
SAC>w over

but, if I try SKS it answered
"traveltime: error finding phase SKS."

    I don't use sss but I was able to reproduce this error with SEISMIC
    ANALYSIS CODE [06/12/2013 (Version 101.6).

    I get the same error in SAC. No problems with S or P, but with SKS.
    Although, I am able to plot the SKS arrival in SAC if the arrival is saved
    to the header in another program i use SOD. If it will work for you, you
    might want to download data with SOD and have the SKS expected arrival
    saved to the header. http://www.seis.sc.edu/sod/index.html

    Example of header from SAC
    http://www.seis.sc.edu/sod/index.html

    NPTS = 5601

    B = 1.399995e+03

    E = 1.539995e+03

    IFTYPE = TIME SERIES FILE

    LEVEN = TRUE

    DELTA = 2.500000e-02

    IDEP = UNKNOWN

    DEPMIN = -6.096525e+02

    DEPMAX = 1.063603e+03

    DEPMEN = 2.185953e+00

    OMARKER = 0

    AMARKER = 1456.5 (SKS)

    T0MARKER = 1512.6 (S)

    T1MARKER = 821.09 (P)

    KZDATE = APR 07 (097), 2015

    KZTIME = 00:46:21.830

    IZTYPE = EVENT ORIGIN TIME

    KSTNM = ACSO
