I want to create a calculated column based on Workflow Status column which the system is not allowing. The error is "One or more column references are not allowed, because the columns are defined as a data type that is not supported in formulas"

I have one more problem here, I have a workflow with more than 10 versions (12 to be exact) of it. All versions have live workflows running. Now I want to check whether the WF is terminated (means in 'Canceled' state) and then I have to show it in a view if its canceled. But WSS 3.0 (dont know about other versions) doesnt allow me to add more than 10 conditions in creating a view. Thats why I thought of creating a calculated column. Even that doesnt work.
