Rclone NSSM - Log

Hi, quick question..

I have Rclone setup as a Service using NSSM using the below argument:

mount gdrive_media_vfs: N: --allow-other --dir-cache-time=160h --cache-chunk-size=10M --cache-info-age=168h --cache-workers=5 --attr-timeout=1s --vfs-read-chunk-size=128M --vfs-cache-max-age=1h --vfs-cache-mode writes --buffer-size=16M --cache-tmp-upload-path "E:\Rclone_Cache\Upload" --cache-tmp-wait-time 30m --cache-db-path "E:\Rclone_Cache\Cache" --log-file "C:\Users\Shenniko.config\rclone\Rclone_Log_Files\Mount.txt" --log-level DEBUG --config "C:\Users\Shenniko.config\rclone\rclone.conf"

I've tried adding a date to the Mount.txt log using Mount_%date:~-4,4%%date:~-7,2%%date:~-10,2%_.txt.. but the service doesnt want to start.. is there a way for me to create a log per day using NSSM to mount Rclone?
