oxf.fr.detail.process for viewing a form?

Is there a process where I can configure how a form is viewed?

I am accessing a form via the form runner like so:

http://localhost:8080/orbeon/fr/cpf/AttachToForm/view/201506112

but I also need to access it like so:

http://localhost:8080/orbeon/fr/cpf/AttachToForm/view/201506112?historical=true

the query parameter changes what data is returned from my persistence layer so I need to have this parameter passed through to the persistence GET request. I do something similar for edit and new forms by configuring the save-final process where I pass through 4 parameters that define where a form is saved in our system.

    <property as="xs:string" name="oxf.fr.detail.process.save-final.cpf.*">
        require-uploads
        then validate-all
        then save(
        query = "{
        if
        (xxf:instance('fr-parameters-instance')/mode = 'new')
        then
        concat(
        string-join(
        for $name in
        ('patientId', 'episodeId', 'sectionId', 'documentCode')
        return
        if
        (exists(xxf:get-request-parameter($name)))
        then
        concat($name,
        '=',encode-for-uri(xxf:get-request-parameter($name)))
        else
        (),
        '&amp;'),
        '&amp;mode=',xxf:instance('fr-parameters-instance')/mode)
        else
        concat('mode=',xxf:instance('fr-parameters-instance')/mode)
        }"
        )
        then
        success-message("save-success")
        then
        navigate(uri= "javascript:window.history.back()")
        recover
        error-message("database-error")
    </property>

Can I do this for a form view process somewhere? I tried configuring this in the review process but it doesn't seem to work.

thanks
