OFSC filter condition: Are we able to use (field/resource) variable in filter condition?

Summary:Today in filter condition, we need to use literal values in value field of the filter condition as far as I know. Would like to know if we can use variable in filter condition

Content (required):For filter condition, we normally use something like this: resource.field in "High". We have a need to use something like: resource.field1 in activity.field1 instead of providing static value in value field. Is this possible?
