SQL & PL/SQL :: Display Grid Output Using Execute Immediate Or SysRefCursor Constructs?

I am in a state of confusion and requires a solution for this urgently:I used to use 'Execute Immediate' statement or 'Sys_RefCursor' for forming parts of query dynamically based on user inputs and then finally execute them at runtime for updating database / saving results into a variable etc.

But as per the latest requirement, I wanted to have the resultset of such a query displayed in the grid area / results area of a database tool; say, SQL Navigator, Toad or PL/SQL developer.; just like you see the results of a normal 'SELECT * FROM TABLE1'; Is this really possible ??

see the below examples:

Eg: for Execute Immediate:

declare
vtest VARCHAR2 := NULL;
vdisplay VARCHAR2;
begin
vtest := 'SELECT FIELD_1 INTO vdisplay FROM TABLE_A';
vtest := trim(vtest) || 'WHERE FIELD_2 = ''XYZ''';
execute immediate TRIM(vtest);
dbms_output.put_line(vdisplay);
end;

---> This would display output into the 'Output' tab of the database tool / editor;

Eg: for SysRefCursor:

declare
vCur SYS_REFCURSOR;
vdisplay VARCHAR2;
begin
OPEN vCur for 'SELECT NULL' || var1 || 'WHERE FIELD_1 = ' || Value1;
FETCH vCur INTO vdisplay;
dbms_output.put_line(vdisplay);
end;

---> Even this would display output only into the 'Output' tab of the database tool / editor;

===> But my requirement is: Different from these, is there any way to get this output displayed into the normal output grid / result area of a database tool ? just like you see the results of a normal 'SELECT * FROM TABLE1' query ?
