Cell Offload will Happen for pl/sql Block with variables

Question

Hello Experts,
i am working on procedures on exadata now. i was confused with cell offload in exadata. somehow offload is not happening when i ran the sql statement in in pl/sql block with variables.
here are my findings.
when i ran insert into from select with values at toad, my query response time is very good. the total process is completed in less than a minute.
i checked offload is happening.
same sql statement is placed in plsql block with variable, procedure is taking lot of time and it is not completing. this case offload is not happening.
is it true, if i use variables in pl/sql block will not use cell offload and smart scan?
if yes, what is the work around.
Thanks
