Does API Support NYSE Symbols With Suffix?

Does API support any of these securities? If so, what are the ticker symbols that I should use?

  1. NYSE preferred stocks. Example: Class-C WFC preferred.
    I tried WFC-C, WFC.C, WFC-PRC, WFC.PRC, WFCPRC and WFCpC. None worked.

  2. NYSE when-issued. Example: BBUC when-issued.
    I tried BBUC-WI, BBUC.WI, BBUCWI and BBUCw. None worked.

  3. NYSE rights offering. Example: CELG rights
    I tried CELG-RT, CELG.RT, CELGRT and CELGr. None worked.
