fieldsToRender add/override options to create method in FormBuilder

hi there I tried to submit functionality for the formbuilder variables
in the dataobjects to be set before the options sent to the create
method. This gives the flexbility of overriding/merging the variables
in the dataobject on a per page basis. For instance I have a label
setup in the dataobject however of a different page I would like the
label to be named different. I have had the same issue for
fieldsToRender where it looks like i have to send the fieldsToRender
option for each page rather than setting is as global then the ability
to override this. Let me know what you think.
