No, it does not appear possible to use special name lists and the documentation does not seem to support it.
Some tips:
Add user-defined formats to CAS with the CASFMTLIB option:
proc format CASFMTLIB = "CASFORMATS";
value $ missfmt ' '="Missing" other="Not Missing";
value nmissfmt .="Missing" other="Not Missing";
run;
Apply formats with the ALTERTABLE action:
proc cas;
table.altertable / columns{{name = "Var1", format = "$missfmt."
{name = "Var2", format = "nmissfmt."}},
name='PROFILE_PORTFOLIO';
action freqTab.freqTab /
table={name='PROFILE_PORTFOLIO', caslib="mkt", ...
