dynamic baseDir and baseUrl set up

Hi,

we are planning to buy the license for CKFinder. But before that we need to know whether there is a solution for this issue,

i want to change the baseDir and baseUrl value dynamically based on the record value i choose to show on. Say if i have some list of records and each record has a directory from which the files should be shown to the user, other files should not be accessible to them. So i need to know whether there is a way in ckfinder to achieve this. I want to change the baseDir dynamically based on the record value. Please let me know about this. As i said we are planning to buy license for ckfinder
