@FAHMY Ayoub (NPO) Thanks for reaching out. As you are using the When a blob is added or modified (properties only) (V2) so your logic app will be triggered for every blob that would be created on the specified path. So as per your workflow so individual email will be sent for each blob that will be created on your path.
To answer your question, you cannot specify the dynamic container path so you need to replace the storage trigger with the event grid trigger and configure event grid subscription on your storage account. Now you can configure the filter condition at the event grid subscription to only send event for specific path using filter condition. For more details, please refer to below document.
