Modifying the container from the roll function

[Vincze Árpád]

Hello workflowers,
 
Is it possible to modify the task container from the roll function?
 
The problem:
 
I have detected in the roll function, that previously selected roll posit=
ion is wrong (can not be used),
 
and I would like to modify the workflow execution path ( I would like to =
realize some kind of escape sequence). For this purpose I would like to s=
end some information from the roll function into the container.
 
I know that I can read the container, but can I write it also from the ro=
ll function, which would be readable at the task execution time?
 
Regards:
