[Zope] Tiny tables

I would like to run some regular reports based upon sqlmethods. The input to these are a mixture of normal values, and some tokenised values. I tried storing these in tiny tables, but it doesn't seem that tiny tables allow one to store tokens. If I specify the value as say, criteria:tokens, it gets changed to just criteria. Any suggestions as to how to store the input as tokens for my reports? -- Graham Chiu
