set a dynamic folder

Hello
I have the following question: I work with Joomla, JCE as editor and when I edit a new article and fill in an image, which I have to upload, then I preset the folder where to store the image according the following rule: images/$year/$month/$day/$user. So every day I have another folder, At the moment the jpg picture is loaded in that dynamic folder but the .webp immage created by your plugin is always put into the image folder. 

Is it possible to preset also an dynamic folder to your plugin? Or in which file of your plugin I have to set the pathname, means including this file via php syntax and then set your path variable by my overrides.
I hope the explanation is clear enough and you have a good solution for me.

Best Regards
