Playback Tokens

I am trying to create KS tokens for video play using AppToken. I am able to create wildcard ones by assigning sview:* to the token privs upon creation but I want to be able to generate entry specific tokens with sview:0_3n4if3f3 type permission. It doesn’t seem like this is possible to set on the apptoken at runtime however. Any ideas?
