[TYPO3-calendar] flexible saveEventToPid?

[Martin Keller]

For only having to create only 1 FE-form (instead of several hundred), I 
would like to link with neccesary parameters to a page with a form and 
create something like

plugin.tx_cal_controller {
   rights.create.event.saveEventToPid = {GP:refpid}
}

Storagepid is given by Link, but I don't think it is evaluated like this.
Is there a way to achieve this somehow?
kind regards,
Martin
