Is is possible to use a cursor as the IN clause of the where clause of a select statement?

I have the following now:

Create Cursor Tasks (taskID I)
Append From Array thisform.snptaskrange1.selecteditems
	
** now build the real cursor
Select * ;
	from rsAllWos ;
	where fk_task_id in (select * from tasks) ;
	into Cursor rsWoTaskSubset

Is there some way to do:

where fk_task_id in (tasks)
